Use variable to trigger function with the same name in javascript (or jQuery)

Question

I have a function with a name, like this:

function tony {
   //do something
}

I also have a variable called currentName with the value 'tony', like this:

var currentName = 'tony';

What I want to know is whether there's any way of activating the tony () function by using the variable currentName eg: +currentName+ (); (but I know that doesn't work)?

Any help would be much appreciated. Thank you.

If it's in the global scope, you can use...

window[currentName]();

This should work:

eval(currentName + '()');

Yeah, I know it should be avoided. Alex's solution is probably also more efficient. :)
