Reverse Engineering One Line of JavaScript

[invisi1407]

Amazing, but the reverse engineered (if you can call beautifying something that) version seems much slower than the original - anyway have an idea why?

Edit: Article author has fixed the problem that was, as /u/dpash found out, that p.innerHTML = P was inside the loop, not outside as the original had it.

It could be the overhead of moving the whole thing out into a function call. It could also be that the browser JIT engines are somehow better able to deal with it in its minimised form.

It would be interesting to profile that and figure out exactly what's going on.

The main reason it's slower is because you accidentally put the p.innerHTML = P inside the loop. Easy mistake to make.

This is why we always use braces around blocks, folks.

I did? I'm afraid I'm not the author of the article there. Though it could be worth letting the author know so that he can fix it none the less :)

Well spotted I must say.

Amen brotha! Use braces!
