Accessing 'this' in Javascript closure

Question

This is more of a sanity check than anything else. I\'ve found that when working with closures in Javascript I often use the following pattern to access the enclosing class

You can pull a sneaky using a binding function like this:

var Binder = function(fnc, obj) {
    return function() {
        fnc.apply(obj, arguments);
    };
};

and then changing your call to

MyClass.prototype.delayed_foo = function() {
    setTimeout(Binder(function(){
        this.foo("Lols");
    },this), 1000);
};
