Nested JavaScript Functions as Objects

The question here is, “should you define a function in the constructor before you assign it as a method, or should you assign it as a method before you define it in the constructor?”

The following two constructor functions are the same.

This one:

function ObjectType()

{

this.propertyType1 = "Yes type one";

function functionType2()

{

alert('This is function type two');

}

this.methodType2 = functionType2;

}

and this one:

function ObjectType()

{

this.propertyType1 = "Yes type one";

this.methodType2 = functionType2;

function functionType2()

{

alert('This is function type two');

}

}

In the first case the function is defined before it is assigned as a method. In the second case it is assigned before it is defined as a method. Both constructor functions work in JavaScript. It does not matter whether you assign the method before you define it, or define it before you assign it.
