Description

JavaScript is the language of the web, and it's the best first language you can learn. This course takes you from absolute beginner to confident developer through short, focused lessons and lots of practice.

Every lesson ends with a tiny exercise you can finish in minutes, so new ideas stick. Along the way you'll build a to-do app, a weather dashboard and a movie finder that you can put straight into your portfolio.

You'll also learn how professional developers think: how to break a problem into steps, how to read error messages and how to find answers on your own. By the end you'll be ready to move on to frameworks like React or to backend work with Node.js.

The course is updated every year for the latest version of JavaScript, and you get every update for free.

The best explanation of async/await I've ever seen. The little exercises after each lesson made everything click. I finally feel like I actually understand JavaScript.

Maya is a fantastic teacher: calm, clear and funny. The weather dashboard project is now the centrepiece of my portfolio.

Great pace for beginners. Section 5 moves a little fast, but the Q&A answers were quick and really helpful.
