Regulex — Visualize Regular Expressions using Javascript

Stumbled upon this today - I love tools that visualize the technology we work with day-by-day. Helps newcomers learn, and improves my own mental model. Another example of a useful tech visualization: SQL Joins Visualizer

Could've used this 10+ years ago when I was back in school! :)

I wish I had this 15 years ago when I used to write RegEx in Pearl scripts for a massive algorithm for speech tech... So cool!

Love this app!
