You can wrap the line:

fade(element);

with setTimeout function:

setTimeout(function () {
    newleft = 0;

    fade(element);
}, 50);

In this case, it means: waiting until the animation is done.

It also because when you run setInterval function, all of the code inside the function will be called imediately. So, if you want to wait 50 miliseconds, you can wrap it with setTimeout .

If you want to repeat the animation for the next click, you can set newleft = 0 inside the setTimeout function.
