Simplify Package

Added

• Better TypeScript support for array flattening

Changed

• Added ES2015 distributable and renamed primary export to exports.flatten

Removed

• Removed array type checked entry to flatten, prefer performance and smaller code
• Removed depth version of functions, if you know the depth it's better to use something like Array#flat or flatten helpers explicitly in code - you typically don't need anything between 1 and infinity in every day code

Readonly TypeScript Array

Fixed

• Use ReadonlyArray for TypeScript interface to improve type assignability

TypeScript Improvements

Changed

• Fix the TypeScript definition return type for depth functions

TypeScript Definition

Added

• Add TypeScript definition to project

Method Error Handling

Changed

• Add TypeError validation to methods
• Split function into four methods - flatten, flattenFrom, flattenDepth and flattenFromDepth

Use Strict

Added

• Perf: 'use strict'

Improved Code Path Performance

Added

• Execute flatten without depth via dedicated code (not depth(Infinity)) to improve performance

Remove Depth 1 Code Path

Fixed

• Remove potential code paths by removing depth === 1 behavior

Updated Documentation

• Updated documentation in README
• Ship on files needed for package
