Free JavaScript Courses

JavaScript runs in every browser, so it's the one language every web developer eventually has to learn, whether you start on the frontend or the backend. Free options here range from beginner-friendly (freeCodeCamp's certificate track, Scrimba's interactive lessons, Khan Academy's animation-based intro) to full frameworks like The Odin Project's Full Stack path and Full Stack Open, which goes deep on React, Redux, GraphQL, and TypeScript. Harvard's CS50 Web Programming course pairs it with Python for a more academic angle. If you're aiming for a job, start with the fundamentals track, then pick one framework path and finish it end to end rather than sampling five.
