JavaScript Roadmap for Beginners
Short answer
JavaScript underpins all frontend work. Learn it in this order to build a solid foundation for interviews.
The fundamentals
Variables (let/const), data types and coercion, functions and scope, arrays and objects, and control flow. Then the concepts interviews love: closures, the this keyword, and prototypes.
Then the harder parts
The event loop, promises and async/await, ES6+ features (destructuring, spread/rest, modules), and array methods (map/filter/reduce). Finish with output questions and implementing utilities (debounce, throttle) to cement understanding.
