What is the difference between the two ways to declare a function in JavaScript?

myFunction : function(variable) 
{

}

or

function myFunction(variable)
{

}

Answer 1

One is a method. The other a function.

Functions are defined

function myfunction() {..}

Methods are defined

myobject.mymethod = function() {...} ;

A method is a property of an object that points to / is a function of that object

Really it depends on how you structure your objects. Functions are usually used in global libraries that are non object specific while methods are tied to objects to execute specific pieces of functionality.
