I am currently trying to learn Javascript and am getting hung up trying to understand Regex. Does anyone have any good resources or recommendations for me?

Regex101.com

also sometimes handy to show railroad diagram to help visualize the pattern.

regex101 is great for building up regex expressions

weve also got a regex community in the instance at !regex@programming.dev with some stuff in it

This isnt really a resource as such, but an interesting game that effectively nerdsniped my whole team:

https://regexlearn.com/ is interactive to get you started.

Then try reading maybe the python regex docs for more detailed info. There are multiple flavors of regex as well, which makes it even more confusing (yay), but you'll eventually grok it enough to make it a part of your toolbox! I use simple regex frequently for search/replace (VScode or vim), and in the shell.

For more complex string parsing operations, there's often a faster/better method than regex, but it's really good to know.

If you like videos then I think this video is quite decent: https://youtu.be/rhzKDrUiJVk?si=UUfyL5ua7FGnGJsL

I just discovered that Exercism.org doesn't have a regex track...

Well, I'll be...
