When should I use call() vs invoking the function directly?

Question

I\'ve got a JavaScript application that uses a lot of callbacks. A typical function will take a callback, and wrap it with another callback.

Namespace.foo = func         


        

Answer 1

Using a function's call() method allows you to changed the object that's bound to the function as this during the execution of the function - this is also called the context

their_on_success.call(myContext, results)

But, if your callback function does not depend on this, it make no difference which way you call it.
