JavaScript Duplicate function names when declaring a method

Question

This is probably a stupid question, but I am hoping to find out from someone who knows better than I do, is there any difference between the following function declarations within a class?

someFunction: function (obj) {};

and

someFunction: function someFunction (obj) {};

first its anonimous, the second are named, there is quite different, so its unclear what do you want know, please add details of your question — invernomuto

Setting a name on an anonymous function allows you to use that name inside the function.

For example:

var funcs = {
    someFunction: function someFunction(obj){
        // you can access 'someFunction' in here
    },
    otherFunction: function(obj){
        // you cannot access 'otherFunction',
        // you'd need to do 'funcs.otherFunction'
    }
};

if you give it a name, is really still anonymous?

@JonathanWilson: I'm not sure how you refer to it, but the function's "name" will only exist inside the function itself, so I guess it's still "anonymous". I don't really know :)

I agree with you overall. I'm just being pedantic I guess ;)

You may be right though. Not sure if it still counts as "anonymous".

Note that you would need a , between someFunction and otherFunction, and a ; at the end would be recommended.
