Arnon RodriguesI am looking to improve the performance of my code through best practices and cleaner code. My goal here is just to perform a conversion whenever there is a keyup. But I noticed that my code looks very repetitive. In your view, what should I do to simplify it? window.oninput = function(event)...

This might be a bad place to ask as well, since you have working code that you want to get reviewed, at least to some extent. A better place for that would be to use codereview.stackexchange.com. There are lots of things in your code which you could improve, even if they are already working. — Ulrich Eckhardt 21 secs ago

Suggest posting this on codereview.stackexchange if your code is working in this form — shree.pat18 5 secs ago
I agree with MisterMiyagi. It would also be to your benefit to show us an example code that more closely represents your case, because the current one was trivial. It also sounds this is an appropriate question for CodeReview SE if your code already works and you just want to improve some aspects of it. — Reti43 15 secs ago
If this is a working solution where you're looking for some improvement, then this might be a better fit over at Code Review. — El_Vanja 49 secs ago

If your code performs what you want it to, the question is off-topic here and should be asked on https://codereview.stackexchange.com/. If it doesn't perform what you want it to, you have to specify what are the differences between expected results and actual results, as well as any errors your code might output. — tao 35 secs ago

Stack Overflow is for asking and answering specific technical questions. "Help me make my program better" isn't quite specific. We're not here to make design decisions for you, but rather, to explain why some particular mechanism works the way it does. You might get more support for this type of query at codereview.stackexchange.com. You'll also want to review the SO help file section covering what's on topic for this site. — MarsAtomic 41 secs ago
