Javascript Silly Question: if-statement syntax

There being a ' ; ' after one and not the other. I was wondering if there was a difference or additional functionality between these 2 if statements?

func(x){  // with a ; at end
    if (false){
        throw new Error('blah');
    };
}

func(x){  // without a ; at end
    if (false){
        throw new Error('blah');
    }
}

There is no differences or additional functionality between the 2 statements

Semicolons are optional in javascript, the interpreter will insert a semicolon at the end of a statement if needed.

In other programming languages like C, the semicolon denotes to the compiler the end of one instruction and the beginning of the next.

There's no difference.

You don't need a ; after a statement block. If you add one, it's just terminating an empty statement, which doesn't do anything.

The first version is probably a typo, it's not normal to put a ; there.
