Snippet: https://gist.github.com/smks/61c3670be194db869b97edc0e89fbd82 http://www.opencanvas.co.uk/ "bind() allows us to easily set which specific object will be bound to this when a function or method is invoked." "The need for bind usually occurs when we use the this keyword in a method and we call that method from a receiver object; in such cases, sometimes this is not bound to the object that we expect it to be bound to, resulting in errors in our applications" References: http://javascriptissexy.com/javascript-apply-call-and-bind-methods-are-essential-for-javascript-professionals/
