Fix messy code and train readability. TypeScript drills on naming, nesting, and magic numbers—with scores and feedback that make clean code click. Readable Code is a training app that helps engineers write code people can actually read. Working code and readable code are not the same thing. In Readable Code, you get intentionally messy TypeScript snippets. You rename, restructure, and simplify them—then submit for a score and concrete feedback. Practice until clean code starts to feel natural. ■ Who it’s for • Engineers told their code is hard to review • Developers who want to practice Clean Code by doing, not just reading • Students, juniors, and self-taught programmers • Anyone polishing coding habits before interviews or real projects ■ What you’ll practice • Clear naming instead of cryptic abbreviations • Removing magic numbers • Flattening deep nesting • Splitting oversized functions • Cleaning up boolean flag arguments • Deduplicating copy-pasted logic • Writing self-documenting code • Replacing careless any types with better design ■ Key features • Filter problems by Easy / Medium / Hard • Edit the starter code right in the app • See an overall score plus naming, structure, simplicity, and comments • Get actionable feedback on what to improve • Track attempts, average score, and best score per problem ■ How to use 1. Pick a difficulty and open a problem 2. Rewrite the hard-to-read code 3. Submit and review your score and feedback 4. Try again and beat your best score Code that works is a start. Code that teammates can read is the goal. Build that skill with Readable Code.
