Javascript Pro

A solid generalist skill for anyone writing modern JavaScript across Node.js and browser environments. It covers the practical async patterns you actually need (promises, async/await, event loop behavior), ES6+ features, and cross-platform compatibility considerations. The focus on preventing callback hell and race conditions shows it's aimed at real-world code quality, not just syntax. Use this when you're working in plain JavaScript and need help with async debugging, migrating legacy code to modern standards, or optimizing performance. It won't help with TypeScript architecture or broader backend design decisions, but for pure JS work with proper error handling and testing patterns, it's a capable starting point.
