How can I stop javascript interpretation after a certain point?

Question

The first few lines of my script look like this:

if (window.location.hash) {
    window.location = window.location.hash.substring(1);
}

I would like the whole script to be skipped if this statement returns true. Is there any way to do this other than putting my entire script in a giant if statement?

Answer 1

Just give it back.

if (window.location.hash) {
    window.location = window.location.hash.substring(1);
    return;
}

Note that the script will still be parsed to the end, so it must be valid JavaScript in its entirety. But I think you meant "interpreted" in the title.
