es5-safe

es5-safe Fork from https://github.com/lifesinger/dew/tree/master/lib/es5-safe。

This module provides compatibility shims so that legacy JavaScript engines behave as closely as possible to ES5.

---

It provides the following methods:

Function.prototype.bind
Object.keys
Array.isArray
Array.prototype.forEach
Array.prototype.map
Array.prototype.filter
Array.prototype.every
Array.prototype.some
Array.prototype.reduce
Array.prototype.reduceRight
Array.prototype.indexOf
Array.prototype.lastIndexOf
String.prototype.trim
Date.now
Date.prototype.toLocaleString
Date.prototype.format

Please refer to MDN for detail usages.

Comparing to kriskowal/es5-shim module, this module only contains the safe parts of ES5 shims, and it is more robust and elegant for old browsers.
