+JSLint, The JavaScript Code Quality Tool
+
+Douglas Crockford
+douglas@crockford.com
+
+2011-12-21
+
+jslint.js contains the fully commented JSLINT function.
+
+jslint.html runs the JSLINT function in a web page. The page also depends
+on adsafe.js [www.ADsafe.org] and json2.js [www.JSON.org] (which are not
+included in this project) and intercept.js and init_ui.js (which are). The
+js files should all be minified, and all except init_ui.js are concatenated
+together to form web_jslint.js.
+
+intercept.js augments ADsafe, giving widgets access to the clock, cookies,
+and the JSLINT function.
+
+init_ui.js hooks the HTML ui components to ADsafe.
+
+lint.html describes JSLint's usage. Please read it.
+
+Direct questions and comments to http://tech.groups.yahoo.com/group/jslint_com/.
+
+JSLint can be run anywhere that JavaScript (or Java) can run. See for example
+http://tech.groups.yahoo.com/group/jslint_com/database?method=reportRows&tbl=1
+
+The place to express yourself in programming is in the quality of your ideas,
+and the efficiency of execution. The role of style is the same as in
+literature. A great writer doesn't express himself by putting the spaces
+before his commas instead of after, or by putting extra spaces inside his
+parentheses. A great writer will slavishly conform to some rules of style,
+and that in no way constrains his power to express himself creatively.
+See for example William Strunk's The Elements of Style
+[http://www.crockford.com/wrrrld/style.html].
+
+This applies to programming as well. Conforming to a consistent style
+improves readability, and frees you to express yourself in ways that matter.
+JSLint here plays the part of a stern but benevolent editor, helping you to
+get the style right so that you can focus your creative energy where it is
+most needed.

+
+JSLint, The JavaScript Code Quality Tool
+
+
+
+
JSLint
+ is a JavaScript program that looks for problems in JavaScript programs.
+ It is a code quality tool.
+
+
When C
+ was a young
+ programming language, there were several common programming errors that
+ were not caught by the primitive compilers, so an accessory program called
+ lint
+ was developed that would scan a source file, looking for problems.
+
+
As the language matured, the definition of the language was
+strengthened to eliminate some insecurities, and compilers got better
+at issuing warnings. lint is no longer needed.
+
+
JavaScript is a young-for-its-age
+ language. It was originally intended to do small tasks in webpages, tasks
+ for which Java was too heavy and clumsy. But JavaScript is a very capable
+ language, and it is now being used in larger projects. Many of the features
+ that were intended to make the language easy to use are troublesome when projects become complicated. A lint for JavaScript is needed: JSLint,
+ a JavaScript syntax checker and validator.
+
+
JSLint takes a JavaScript source and scans it. If it finds
+ a problem, it returns a message describing the problem and an approximate
+ location within the source. The problem is not necessarily a syntax error,
+ although it often is. JSLint looks at some style conventions
+ as well as structural problems. It does not prove that your program is
+ correct. It just provides another set of eyes to help spot problems.
JavaScript is a sloppy language, but inside it there is an elegant, better
+ language. JSLint helps you to program in that better language
+ and to avoid most of the slop. JSLint will reject programs that browsers will accept because JSLint is concerned with the quality of your code and browsers are not. You should accept all of JSLint's advice.
+
JSLint can operate on JavaScript source, HTML source, CSS source, or JSON
+ text.
+
Global Variables
+
JavaScript's biggest
+ problem is its dependence on global variables, particularly implied
+ global variables. If a variable is not explicitly declared (usually with
+ the var statement), then JavaScript assumes that the variable
+ was global. This can mask misspelled names and other problems.
+
JSLint expects that all variables and functions are declared
+ before they are used or invoked. This allows it to detect implied global
+ variables. It is also good practice because it makes programs easier to
+ read.
+
Sometimes a file is dependent on global variables and functions that
+ are defined elsewhere. You can identify these to JSLint with a var statement that lists the global functions and objects
+ that your program depends on.
+
A global declaration can look like this:
+
var getElementByAttribute, breakCycles, hanoi;
+
The declaration should appear near the top of the file. It must appear before the use of the variables
+ it declares.
+
It is necessary to use a var statement to declare a variable before that variable is assigned to.
+
JSLint also recognizes a /*global */ directive that can indicate to JSLint that variables used in this file were defined in other files. The comment can contain a comma separated list of names. Each name can optionally be followed by a colon and either true or false, true indicating that the variable may be assigned to by this file, and false indicating that assignment is not allowed (which is the default). The directive respects function scope.
+
Some globals can be predefined for you. Select the Assume
+ a browser (browser) option to
+ predefine the standard global properties that are supplied by web browsers,
+ such as document and addEventListener. It has the same
+ effect as this comment:
Select the
+ Assume console, alert, ...
+(devel) option to predefine globals that are useful in development but that should be avoided in production, such as console and alert. It has the same
+effect as this comment:
Select the Assume Rhino (rhino) option
+ to predefine the global properties provided by the Rhino environment.
+ It has the same effect as this statement:
Select the Assume a Yahoo Widget (widget)
+ option to predefine the global properties provided
+ by the Yahoo! Widgets environment. It has the same effect as this statement:
Select the Assume Windows (windows)
+ option to predefine the global properties provided by Microsoft Windows. It has the same effect as this statement:
JavaScript uses a C-like syntax which requires the use of semicolons to delimit certain
+ statements. JavaScript attempts to make those semicolons optional with a semicolon
+ insertion mechanism. This is dangerous because it can mask errors.
+
Like C, JavaScript has ++ and -- and ( operators
+ which can be prefixes or suffixes. The disambiguation is done by the semicolon.
+
In JavaScript, a linefeed can be whitespace or it can act as a semicolon.
+ This replaces one ambiguity with another.
+
JSLint expects that every statement be followed by ; except
+ for for, function, if, switch, try, and
+ while. JSLint does not expect to see unnecessary semicolons or the
+ empty statement.
+
Comma
+
The comma operator can lead to excessively tricky expressions. It can also
+ mask some programming errors.
+
JSLint expects to see the comma used as a separator, but not as an
+ operator (except in the initialization and incrementation parts of the for
+ statement). It does not expect to see elided elements in array literals. Extra
+ commas should not be used. A comma should not appear after the last element
+ of an array literal or object literal because it can be misinterpreted by some
+ browsers.
+
Scope
+
+
In many languages, a block introduces a scope. Variables introduced in
+ a block are not visible outside of the block.
+
+
In JavaScript, blocks do not introduce a scope. There is only function-scope.
+ A variable introduced anywhere in a function is visible everywhere in
+ the function. JavaScript's blocks confuse experienced programmers and
+ lead to errors because the familiar syntax makes a false promise.
+
+
JSLint expects blocks with function, if,
+ switch, while, for, do,
+ and try statements and nowhere else.
+
In languages with block scope, it is usually recommended that variables
+ be declared at the site of first use. But because JavaScript does not
+ have block scope, it is wiser to declare all of a function's variables
+ at the top of the function. It is recommended that a single var
+ statement be used per function. This can be declined with the vars
+ option.
+
+
Required Blocks
+
+
JSLint expects that if, while,
+ do and for statements will be made with blocks
+ {that is, with statements enclosed in braces}.
+
+
JavaScript allows an if to be written like this:
+
+
if (condition)
+ statement;
+
+
That form is known to contribute to mistakes in projects where many programmers
+ are working on the same code. That is why JSLint expects the use of
+ a block:
+
+
if (condition) {
+ statements;
+}
+
+
Experience shows that this form is more resilient.
+
+
Expression Statements
+
An expression statement is expected to be an assignment or a function/method
+ call or delete. All other expression statements are considered
+ to be errors.
+
Type Confusion
+
JSLint can do type inference. It can report cases were variables and properties are
+used to house multiple types. The warning is Type confusion: {a} and {b}. where the {a} and {b} will be
+replaced with the names of types.
+
It is usually easy to see what caused the
+ warning. In some cases, it can be very puzzling. In the puzzling cases, try
+ initializing your vars with typed values. For example, if you expect that n will
+ contain numbers, then write
+
var n = 0;
+
That should produce clearer warnings.
+
Type confusion is not necessarily an error, particularly in a language that
+ provides as much type freedom as this one does. But some inconsistencies are
+ errors, so type discipline might be something to consider adding to your
+ programming style. Also, the fastest JavaScript engines will slow down in the
+ presence of type confusion.
+
+ To turn off these warnings, turn on the Tolerate type confusionoption.
The body of every forin statement should be
+ wrapped in an if statement that does filtering. It can select
+ for a particular type or range of values, or it can exclude functions,
+ or it can exclude properties from the prototype. For example,
+
for (name in object) {
+ if (object.hasOwnProperty(name)) {
+ ....
+ }
+
+}
+
+
switch
+
A common
+ error in switch statements is to forget to place a break
+ statement after each case, resulting in unintended fall-through. JSLint
+ expects that the statement before the next case or default
+ is one of these: break, return, or throw.
+
+
var
+
+
JavaScript allows var definitions to occur anywhere
+ within a function. JSLint is more strict.
+
+
JSLint expects that a var will be declared
+ only once, and that it will be declared before it is used.
+
JSLint expects that a function
+ will be declared before it is used.
+
JSLint expects that parameters will not also be declared
+ as vars.
+
+
JSLint does not expect the arguments array to be declared
+ as a var.
+
JSLint does not expect that a var will be defined in a block.
+ This is because JavaScript blocks do not have block scope. This can have
+ unexpected consequences. Define all variables at the top of the function.
+
+
with
+
+
The with statement was intended to provide a shorthand in accessing
+ properties in deeply nested objects. Unfortunately, it behaves very
+ badly when setting new properties. Never use the with statement. Use
+ a var instead.
+
+
JSLint does not expect to see a with statement.
+
+
=
+
JSLint does not expect to see an assignment statement in
+ the condition part of an if or for or while
+ or do statement. This is because it is more
+ likely that
+
if (a = b) {
+ ...
+}
+
was intended to be
+
if (a == b) {
+ ...
+}
+
It is difficult to write correct programs while using idioms that are
+ hard to distinguish from obvious errors.
+
== and !=
+
The == and != operators do type coercion before
+ comparing. This is bad because it causes ' \t\r\n' == 0 to
+ be true. This can mask type errors. JSLint cannot reliably determine if == is being used correctly, so it is best to not use == and != and to always use the more reliable === and !== operators instead.
+
If you only care that a value is truthy or falsy,
+ then use the short form. Instead of
+
(foo != 0)
+
just say
+
(foo)
+
and instead of
+
(foo == 0)
+
say
+
(!foo)
+
There is an eqeqoption that allows the use of == and !=.
+
Labels
+
JavaScript allows any statement to have a label, and labels have a
+ separate name space. JSLint is more strict.
+
+
JSLint expects labels only on statements that interact
+ with break: switch, while,
+ do, and for. JSLint expects that labels
+ will be distinct from vars and parameters.
+
+
Unreachable Code
+
JSLint expects that
+ a return, break, continue,
+ or throw statement will be followed by
+ a } or case or default.
+
+
Confusing Pluses and Minuses
+
+
JSLint expects that + will not be followed by
++ or ++, and that - will not be followed
+by - or --. A misplaced space can turn + + into ++, an error that is difficult to see. Use parens to avoid confusion..
+
++ and --
+
The ++ (increment) and -- (decrement)
+ operators have been known to contribute to bad code by encouraging excessive
+ trickiness. They are second only to faulty architecture in enabling to
+ viruses and other security menaces. Also, preincrement/postincrement confusion can produce off-by-one errors that are extremely difficult to diagnose. There is a plusplusoption
+ that allows the use of these operators.
+
Bitwise Operators
+
JavaScript does not have an integer type, but it does have bitwise operators.
+ The bitwise operators convert their operands from floating point to integers
+ and back, so they are not as efficient as in C or other languages. They
+ are rarely useful in browser applications. The similarity to the logical
+ operators can mask some programming errors. The bitwiseoption
+ allows the use of these operators: << >> >>>
+ ~ & |.
+
eval is evil
+
The eval function (and its relatives, Function,
+ setTimeout, and setInterval) provide access
+ to the JavaScript compiler. This is sometimes necessary, but in most cases
+ it indicates the presence of extremely bad coding. The eval
+ function is the most misused feature of JavaScript.
+
+
void
+
In most C-like languages, void is a type. In
+ JavaScript, void is a prefix operator that always
+ returns undefined. JSLint does not expect to
+ see void because it is confusing and not very useful.
+
+
Regular Expressions
+
Regular expressions are written in a terse and cryptic notation. JSLint
+ looks for problems that may cause portability problems. It also attempts
+ to resolve visual ambiguities by recommending explicit escapement.
+
JavaScript's syntax for regular expression literals overloads the /
+ character. To avoid ambiguity, JSLint expects that the character
+ preceding a regular expression literal is a ( or =
+ or : or , character.
+
Constructors and new
+
Constructors are functions that are designed to be used with the new
+ prefix. The new prefix creates a new object based on the
+ function's prototype, and binds that object to the function's
+ implied this parameter. If you neglect to use the new
+ prefix, no new object will be made and this will be bound
+ to the global object. This is a serious
+ mistake.
+
JSLint enforces the convention that constructor functions
+ be given names with initial uppercase. JSLint does not expect
+ to see a function invocation with an initial uppercase name unless it
+ has the new prefix. JSLint does not expect to
+ see the new prefix used with functions whose names do not
+ start with initial uppercase. This can be disabled with the newcap
+ option.
+
JSLint does not expect to see the wrapper forms new Number,
+ new String, new Boolean.
+
JSLint does not expect to see new Object (use {}
+ instead).
+
JSLint does not expect to see new Array (use []
+ instead).
+
Type Inference
+
Type inference is being added to JSLint. The goal is to ultimately make JSLint more helpful in spotting type inconsistencies and confusions. If you do not want this service, then select the confusionoption.
+
+
Properties
+
Since JavaScript is a loosely-typed, dynamic-object language, it is not
+ possible to determine at compile time if property names are spelled correctly.
+ JSLint provides some assistance with this.
+
At the bottom of its report, JSLint displays a /*properties*/
+ comment. It contains all of the names and string literals that were used
+ with dot notation, subscript notation, and object literals to name the
+ properties of objects. You can look through the list for misspellings. Property
+ names that were only used once are shown in italics. This is to make misspellings
+ easier to spot.
+
You can copy the /*properties*/ comment into your script file.
+ JSLint will check the spelling of all property names against
+ the list. That way, you can have JSLint look for misspellings
+ for you. The directive respects function scope.
+
JSLint allows the property names to be annotated with types: array, boolean, function, number, object, regexp, string, or * (a wildcard allowing any type). A function type can be followed by another type, indicating a function's return type.
+
For example,
+
/*properties
+ charAt: function string, slice: function *
+*/
+
+
Unsafe Characters
+
There are characters that are handled inconsistently in browsers, and
+ so must be escaped when placed in strings.
JSLint does not do flow analysis to determine that variables are assigned
+ values before used. This is because variables are given a value (undefined)
+ that is a reasonable default for many applications.
JSLint is able to handle HTML text. It can inspect the JavaScript content
+ contained within <script>...</script> tags. It
+ also inspects the HTML content, looking for problems that are known to interfere
+ with JavaScript:
+
+
All tag names must be in lower case.
+
All tags that can take a close tag (such as </p>)
+ must have a close tag.
+
All tags are correctly nested.
+
The entity < must be used for literal '<'.
+
+
JSLint is less anal than the sycophantic conformity demanded
+ by XHTML, but more strict than the popular browsers.
+
JSLint also checks for the occurrence of '</' in
+ string literals. You should always write '<\/' instead.
+ The extra backslash is ignored by the JavaScript compiler but not by the
+ HTML parser. Tricks like this should not be necessary, and yet they are.
+
There is a capoption that allows
+ use of uppercase tag names. There is also an onoption
+ that allows the use of inline HTML event handlers.
+
There is a fragmentoption that can
+ inspect a well formed HTML fragment. If the adsafeoption
+ is also used, then the fragment must be a <div> that
+ conforms to the ADsafe widget rules.
+
CSS
+
JSLint can inspect CSS files. It expects the first line
+ of a CSS file to be
+
@charset "UTF-8";
+
This feature is experimental. Please report any problems or limitations.
+ There is a cssoption that will tolerate
+ some of the non-standard-but-customary workarounds.
+
+
Options
+
JSLint provides several options that control its operation and
+ its sensitivity. In the web edition, the
+options are selected with several checkboxes and two fields.
+
It also provides assistance in constructing /*jslint*/
+ comments.
+
+
When JSLINT is called as a function, it accepts an option object
+ parameter that allows you to determine the subset of JavaScript that is
+ acceptable to you. The web page version of JSLint at http://www.JSLint.com/
+ does this for you.
+
Options can also be specified within a script with a /*jslint */
+ directive:
An option specification starts with /*jslint. Notice that
+ there is no space before the j. The specification contains
+ a sequence of name value pairs, where the names are JSLint
+ options, and the values are true or false. The
+ indentoption can take a number. A /*jslint */
+ comment takes precedence over the option object. The directive respects function scope.
+
+
+

true if ES5 syntax should be allowed.
+ It is likely that programs using this option will produce syntax errors on ES3 systems.
An array of strings, the names of predefined global variables, or an object whose keys are global variable names, and whose values are booleans that determine if each variable is assignable (also see global). predef is used with the option object, but not

true if the Rhino
+ environment globals should be predefined. (more)
+
+

+
+
+
Tolerate many var statements per function
+
vars
+
true if multiple var statement per function

Please let me know if JSLint is useful for you. Is it too
+ strict? Is there a check or a report that could help you to improve the
+ quality of your programs?
+ douglas@crockford.com.
+ But please don't ask me to dumb JSLint down or to make it more
+ forgiving of bad practices. You would only be disappointed.
Try it. Paste your script
+ into the window and click the
+
+ button. The analysis is done by a script running on your machine.
+ Your script is not sent over the network. You can set the options used.

+
+// WARNING: JSLint will hurt your feelings.
+
+// JSLINT is a global function. It takes two parameters.
+
+// var myResult = JSLINT(source, option);
+
+// The first parameter is either a string or an array of strings. If it is a
+// string, it will be split on '\n' or '\r'. If it is an array of strings, it
+// is assumed that each string represents one line. The source can be a
+// JavaScript text, or HTML text, or a JSON text, or a CSS text.
+
+// The second parameter is an optional object of options that control the
+// operation of JSLINT. Most of the options are booleans: They are all
+// optional and have a default value of false. One of the options, predef,
+// can be an array of names, which will be used to declare global variables,
+// or an object whose keys are used as global names, with a boolean value
+// that determines if they are assignable.
+
+// If it checks out, JSLINT returns true. Otherwise, it returns false.
+
+// If false, you can inspect JSLINT.errors to find out the problems.
+// JSLINT.errors is an array of objects containing these properties:
+
+// {
+// line : The line (relative to 0) at which the lint was found
+// character : The character (relative to 0) at which the lint was found
+// reason : The problem
+// evidence : The text line in which the problem occurred
+// raw : The raw message before the details were inserted
+// a : The first detail
+// b : The second detail
+// c : The third detail
+// d : The fourth detail
+// }
+
+// If a stopping error was found, a null will be the last element of the
+// JSLINT.errors array. A stopping error means that JSLint was not confident
+// enough to continue. It does not necessarily mean that the error was
+// especially heinous.
+
+// You can request a Function Report, which shows all of the functions
+// and the parameters and vars that they use. This can be used to find
+// implied global variables and other problems. The report is in HTML and
+// can be inserted in an HTML .
+
+// var myReport = JSLINT.report(errors_only);
+
+// If errors_only is true, then the report will be limited to only errors.
+
+// You can request a data structure that contains JSLint's results.
+
+// var myData = JSLINT.data();
+
+// It returns a structure with this form:
+
+// {
+// errors: [
+// {
+// line: NUMBER,
+// character: NUMBER,
+// reason: STRING,
+// evidence: STRING
+// }
+// ],
+// functions: [
+// {
+// name: STRING,
+// line: NUMBER,
+// last: NUMBER,
+// params: [
+// {
+// string: STRING
+// }
+// ],
+// closure: [
+// STRING
+// ],
+// var: [
+// STRING
+// ],
+// exception: [
+// STRING
+// ],
+// outer: [
+// STRING
+// ],
+// unused: [
+// STRING
+// ],
+// undef: [
+// STRING
+// ],
+// global: [
+// STRING
+// ],
+// label: [
+// STRING
+// ]
+// }
+// ],
+// globals: [
+// STRING
+// ],
+// member: {
+// STRING: NUMBER
+// },
+// urls: [
+// STRING
+// ],
+// json: BOOLEAN
+// }
+
+// Empty arrays will not be included.
+
+// You can obtain the parse tree that JSLint constructed while parsing. The
+// latest tree is kept in JSLINT.tree. A nice stringication can be produced
+// with
+
+// JSON.stringify(JSLINT.tree, [
+// 'string', 'arity', 'name', 'first',
+// 'second', 'third', 'block', 'else'
+// ], 4));
+
+// JSLint provides three directives. They look like slashstar comments, and
+// allow for setting options, declaring global variables, and establishing a
+// set of allowed property names.
+
+// These directives respect function scope.
+
+// The jslint directive is a special comment that can set one or more options.
+// The current option set is
+
+// anon true, if the space may be omitted in anonymous function declarations
+// bitwise true, if bitwise operators should be allowed
+// browser true, if the standard browser globals should be predefined
+// cap true, if upper case HTML should be allowed
+// confusion true, if types can be used inconsistently
+// 'continue' true, if the continuation statement should be tolerated
+// css true, if CSS workarounds should be tolerated
+// debug true, if debugger statements should be allowed
+// devel true, if logging should be allowed (console, alert, etc.)
+// eqeq true, if == should be allowed
+// es5 true, if ES5 syntax should be allowed
+// evil true, if eval should be allowed
+// forin true, if for in statements need not filter
+// fragment true, if HTML fragments should be allowed
+// indent the indentation factor
+// maxerr the maximum number of errors to allow
+// maxlen the maximum length of a source line
+// newcap true, if constructor names capitalization is ignored
+// node true, if Node.js globals should be predefined
+// nomen true, if names may have dangling _
+// on true, if HTML event handlers should be allowed
+// passfail true, if the scan should stop on first error
+// plusplus true, if increment/decrement should be allowed
+// properties true, if all property names must be declared with /*properties*/
+// regexp true, if the . should be allowed in regexp literals
+// rhino true, if the Rhino environment globals should be predefined
+// undef true, if variables can be declared out of order
+// unparam true, if unused parameters should be tolerated
+// sloppy true, if the 'use strict'; pragma is optional
+// sub true, if all forms of subscript notation are tolerated
+// vars true, if multiple var statements per function should be allowed
+// white true, if sloppy whitespace is tolerated
+// widget true if the Yahoo Widgets globals should be predefined
+// windows true, if MS Windows-specific globals should be predefined
+
+// For example:
+
+/*jslint
+ evil: true, nomen: true, regexp: true
+*/
+
+// The properties directive declares an exclusive list of property names.
+// Any properties named in the program that are not in the list will
+// produce a warning.
