Understanding JavaScript’s Function.prototype.bind

Function binding is probably your least concern when beginning with JavaScript, but when you realize that you need a solution to the problem of how to keep the context of this within another function, then you might not realize that what you actually need is Function.prototype.bind().

render: function () {

    this.getAsyncData(function () {





The first time you hit upon the problem, you might be inclined to set this to a variable that you can reference when you change context.
