Answer 1

bind function might be what you're looking for, bind function returns a new function with in the context that you passed in , a real world scenario could be when you are using jquery delegates to attach some behavior to a dom element, and you want the callback being execute in a different context. 'cause the default context in a jquery delgate is the dom object that is bound to the handler , which means you can't access any property besides the properties that belongs to the dom object
