[javascript] Javascript wait() function

I want to create a JavaScript wait() function.

What should I edit?

function wait(waitsecs) {
    setTimeout(donothing(), 'waitsecs');
}

function donothing() {
    //
}

You shouldn't edit it, you should completely scrap it.

Any attempt to make execution stop for a certain amount of time will lock up the browser and switch it to a Not Responding state. The only thing you can do is use setTimeout correctly.
