How to get method name from JavaScript file

Question

I have a JavaScript file with many methods defined in it. Is there any way to know how many methods are in that file & what are the names of methods?

Answer 1

While, in theory, you could try to find everything that matched the pattern:

function (

You'd be missing out on a lot of other types of functions. See, Functions are really just objects in JavaScript. They can be assigned, shared, modified, and moved around. So, you'd also have to find these:

var  = function() {}

And these:

function returnFunc() {
    return function() {...}
}
var  = returnFunc();

As well as these:

obj.member = new Function();

And a nearly infinite variety of similar function definitions.

So, the answer is, most likely you can't. Unless the code is extremely narrowly constructed.
