ECMAScript compatibility shims for legacy JavaScript engines

`es5-shim.js` monkey-patches a JavaScript context to contain all EcmaScript 5 methods that can be faithfully emulated with a legacy JavaScript engine.

es5-sham.js monkey-patches other ES5 methods as closely as possible. For these methods, as closely as possible to ES5 is not very close. Many of these shams are intended only to allow code to be written to ES5 without causing run-time errors in older engines. In many cases, this means that these shams cause many ES5 methods to silently fail. Decide carefully whether this is what you want. Note: es5-sham.js requires es5-shim.js to be able to work properly.

json3.js monkey-patches the EcmaScript 5 JSON implimentation faithfully.

es6.shim.js provides compatibility shims so that legacy JavaScript engines behave as closely as possible to ECMAScript 6 (Harmony).

module.exports([nonWhiteSpace], [escaped]) ⇒ string ⏏

Generate a string of ES5 (non-)whitespaces, optionally escaped for use with new RegExp.

Kind: Exported function
Returns: string - The generated string.

Param	Type	Default	Description
[nonWhiteSpace]	boolean	false	Generate a string of non-whitespaces.
[escaped]	boolean	false	Generate an escaped string.

Example

var generateString = require('white-space-x');
var ws = generateString();
var nonWs = generateString(true);

var re1 = new RegExp('^[' + generateString(false, true) + ']+$)');
re1.test(ws); // true

var re2 = new RegExp('[' + generateString(false, true) + ']$)');
re2.test(nonWs); // false

module.exports~whiteSpaces : Array.<number>

An array of the whitespace char codes.

Kind: inner property of module.exports

module.exports~escape(string) ⇒ string

This method takes a string and puts a backslash in front of every character that is part of the regular expression syntax. This is useful if you have a run-time string that you need to match in some text and the string may contain special regex characters.

Kind: inner method of module.exports
Returns: string - The escaped string.

Param	Type	Description
string	string	The string to be escaped.
