JS Playground

A playground for JavaScript/TypeScript code challenges, experiments, and quick prototypes.

Project Structure

• src/code_challenges/ — Self-contained coding challenge folders, each with a README.md, solution, and co-located tests.
• src/experiments/ — Ad-hoc scripts, spikes, and quick tests.
• src/lib/ — Shared utilities reused across challenges or experiments.
• tests/ — Integration tests, or tests for experiments that don't fit inside src/.

Quick Start

# Install dependencies
pnpm install

# Run all tests
pnpm test

# Run tests in watch mode
pnpm test:watch

# Lint code
pnpm run lint

# Auto-fix lint issues
pnpm run lint:fix

# Format code
pnpm run format

Adding a New Challenge

1. Create a new folder under src/code_challenges/ (e.g., 05-new-challenge/).
2. Add README.md, solution.ts, and solution.test.ts.
3. Export your function from solution.ts and import it in solution.test.ts.
4. Run pnpm test to verify.
