webkit-assign-loader

Due to [WebKit issue #138038][], assigning to a property on an object created with Object.create may result in the error TypeError: Attempted to assign to readonly property.. This bug is known to affect iOS 8 users and is particularly likely to happen in recent versions of [Angular.js].

This utility rewrites the following code

object.$$a = 5;

to this

var __webkitAssign__$$a = '$$a';
object[__webkitAssign__$$a] = 5;

as a workaround to prevent a TypeError.
