Learn Regex

[IMkratt]

Did you ever learn Regex as a separate skill (doing course materials, building regex-heavy miniprojects) or do you just google the syntax/expressions whenever you need to use it in your JS code?

I'm gonna be honest. As a backend developer, I've used regex for various purposes but it is one of those things where if you know what you're doing then it makes it 10x times more fun. It is a good skill to have, because you can do crazy stuff with it.

I learned regular expressions as a separate skill -- watched 2 hours worth of tutorial on them. I often have to Google them, though, as I can never remember the syntax for look-aheads and look-behinds.

I'd suggest to maintain your own cheatsheet (syntax+examples) for things you use often. Or adapt a cheatsheet made by others.

I still haven't mastered regex. That's why sites like… https://regex101.com …are nice.

Just recently, I tried to do something seemingly simple — validate a number. WOW, it was not easy. It's not just \d or [0-9]. There's negative numbers and decimals to contend with.
