How to put a function inside an object and directly output the result

Question by Dan Myasnikov

Look, I ve got the following code to be executed and the result expected:

a = { a: function(){ return 'red'} }

so whenever I call

a.a #=> I would like to receive 'red' rather than 'function(){ return 'red'}

Any help appreciated

Answer by Starx

Simply do this

a = { 
   a: 'red' 

But if having the result return function that important, we have to make sure the function get called and returned.

a = {
    a: function() {
        return 'red-by-function';
    }() //This will ensure the function is called rather that returning the whole function

Demo of both cases
