Category
JavaScript Fundamentals
Description
Regex Golf is an interactive quest that teaches regular expressions through progressively challenging puzzles.
Players are given two sets of strings:
- ✅ Must Match
- ❌ Must Not Match
Their objective is to write the shortest regular expression that correctly matches all valid strings while rejecting the invalid ones. Each level introduces new regex concepts such as literals, character classes, quantifiers, anchors, groups, alternation, and lookaheads, helping learners understand regex by experimentation rather than memorization.
Key Features
- 10 progressively harder regex challenges
- "Must Match" and "Must Not Match" string sets
- Live regex validation while typing
- Character count with shorter regex rewarded
- Star-based scoring system
- Hint system for difficult levels
- Explanation after completing each challenge
- Progress saved using localStorage
- Responsive and keyboard accessible
- Works completely offline
