What is the Correct Javascript Syntax for this

Question

I am trying to call a function within a function. Here is the code

var d = function() {
    s: function() {
        alert('cool');
    }
} ();
d.s();

This does not work. What am I doing wrong

Answer 1

var d = {
  s: function() {
    alert('cool');
  }
};

d.s();

Answer 2

Erm... it looks like maybe you're trying to define an Object with a function?

In that case,

var d = {
  s: function(){
    alert('cool');
  }
};
d.s();  //Invokes the function s

Answer 3

Here is another approach using the so-called module pattern:

var d = function() {
  return {
    s: function() {
      alert('cool');
    }
  };
}();
d.s();  // invokes the function s
