About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isObjectLike

Test if a value is object-like.

Installation

npm install @stdlib/assert-is-object-like

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var isObjectLike = require( '@stdlib/assert-is-object-like' );

isObjectLike( value )

Tests if a value is object-like.

var bool = isObjectLike( {} );
// returns true

bool = isObjectLike( [] );
// returns true

bool = isObjectLike( true );
// returns false

isObjectLike.isObjectLikeArray( value )

Tests if a value is an array of object-like values.

var bool = isObjectLike.isObjectLikeArray( [ {}, [] ] );
// returns true

bool = isObjectLike.isObjectLikeArray( [ {}, '3.0' ] );
// returns false

bool = isObjectLike.isObjectLikeArray( [] );
// returns false

Notes

• Return values are the same as would be obtained using the built-in typeof operator except that null is not considered an object.

  var bool = ( typeof null === 'object' );
  // returns true
  
  bool = isObjectLike( null );
  // returns false

Examples

var Int8Array = require( '@stdlib/array-int8' );
var ArrayBuffer = require( '@stdlib/array-buffer' );
var isObjectLike = require( '@stdlib/assert-is-object-like' );

var bool = isObjectLike( {} );
// returns true

bool = isObjectLike( [] );
// returns true

bool = isObjectLike( /./ );
// returns true

bool = isObjectLike( new Date() );
// returns true

bool = isObjectLike( Math );
// returns true

bool = isObjectLike( JSON );
// returns true

bool = isObjectLike( new Int8Array() );
// returns true

bool = isObjectLike( new ArrayBuffer() );
// returns true

bool = isObjectLike( 'a' );
// returns false

bool = isObjectLike( 5 );
// returns false

bool = isObjectLike( null );
// returns false

bool = isObjectLike( void 0 );
// returns false

bool = isObjectLike( function foo() {} );
// returns false
