Question

Was working on some js code performance and saw this approach:

window.sample = {

    foo: function foo(a,b){
       // code goes here
    }

    bar: function bar(a,b){
       // code goes here
    }

}

is there any reason why you would decelerate the function name after the word “function” ?

dose it help to debug?

is it good or bad or just unnecessary?

Answer 1

instead of assigning an anonymous function to the foo and bar properties, they are assigning named functions.

it can be helpful for debugging: the only difference this makes, that i know of, is that you will see the names of the functions show up in the call stack instead of “javascript anonymous function”
