JavaScript semicolon after a function

Question

I wonder the difference between two codes below in JavaScript, welcome answer.

Code 1:

function Add(a,b) {
    return a + b;
}

Code 2:

function Add(a,b) {
    return a + b;
};

The difference is that one has a semicolon after it and one doesn't. The semicolon after the function is not needed. — Steve, Jan 15 '14 at 07:18

The second code contains an empty statement. You can add as many as you want.

function Add(a,b) {
    ;;;;;
    return a + b;;;;;;;
};;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

There is no difference. The ; in the second example just creates an empty statement there.

First one is the standard method

Second one is not recommended.. Use the first method
