Phil
ES5 polyfill
Provides ECMAScript 5 compatibility on specific methods of native JavaScript objects. Some are full rewrites, like Object.create
or Function.bind
, others are workarounds for browser quirks, like argument handling in Array.sort
, or negative indexes for String.substr
.
Getters and setters are only partially emulated in browsers where no substitute is available (eg. IE8). Here the chosen behavior is that getters and setters are accepted by Object.defineProperty
, but the getter is immediately evaluated and its result assigned to the property as value.
At this point Phil is not a complete polyfill, as it implements only those methods that are required by Troop-based libraries.
