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

The only reason to use call (or apply) is if you want to set the value of this inside the function.

Well, I guess apply can be useful in other cases as it accepts an array of parameters.
