A guy on my team today shared this, and I had to immediately share as well. Regular Expression (RegEx) is super powerful, but can be very confusing, and a single character off can have big consequences, not work properly or cause a regular expression to fail completely.
It’s cool in that as you put in RegEx, it code hints everything so you can fully understand everything in the string — which is nice when you find a possible solution on Stack Overflow or some other random development blog. It helps you parse out what the RegEx is actually doing.
The explanations are well done and it’s a tool I’m definitely bookmarking for the next time I’m in the regular expression world.
