What’s the difference in those declarations (in JavaScript)?

Is there any differences between the following function declarations:

function wtf() {

}

lol = function() {

}

omg: function() {

}

?

Regards

Answer 1

1- Is a regular function declaration.

2- You declare an anonymous function and you store it in a variable.

3- The last one is part of an object notation :

var obj = {
  omg:function(value){
    // some code here
  }
};

Answer 2

1st one :

creates a function at page level ( global level u can say )

2nd : Assings the function to variable 'lol'

3rd: Syntax error. :P
