Love it! Probably the best tool I've used for learning, testing, and implementing regexs
I use Perplexity and have found it all I needfor Regex.. but I'm not proficient. Anyone compared it?
Incredibly detailed highlighting of groups is very helpful.
I gave
RegExr for a spin which I liked as well
Between what I read on stackoverflow and reddit, these two were highly recommended
But regex101 feels way more robust in my opinion when it comes to selecting statements that match the regex expression
Regexr... not so much. Maybe these were just my initial impressions but alot of regex's community suggestion snippets didn't work some reason
Regex101 (this one) lets you save your regex snippets (e.g. text sample input and the regex command) so its a nice library reference I can use on later
I find the cheatsheets on regex101 to be better and easier to look at then regexr
