JavaScript Fundamentals

Part of the Full Stack Developer Roadmap

In short

Variables, functions, objects, arrays and control flow — the core language you'll write on both sides of a full-stack app, since Node.js runs the same JavaScript your browser does.

How to learn this

1Practice array methods (`map`, `filter`, `reduce`) until they're second nature.
2Write functions using both function declarations and arrow function syntax.
3Focus on destructuring and spread/rest — they show up constantly in both React and Node code.
