What it does
Regex Learn combines regular-expression instruction, a pattern cheatsheet and a testing playground.
Use the lessons for a new construct, then move to the playground to test it against your own text. The cheatsheet is a quicker route when you remember the idea but have forgotten a symbol. Keeping those three tasks together helps you move between explanation, recall and experimentation. The site is free to use. Its separate Practice section is still marked as coming soon; the available learning lessons and playground are the routes to use now.
