About this course

JavaScript is a powerful programming language. But as it continues to evolve, outdated code gets messy and difficult to maintain. That’s where TypeScript comes in. It builds on your JavaScript foundation so you can develop higher-quality, less error-prone code faster. As a TypeScript developer, you’ll be in higher demand and gain a competitive edge in the work world.

  • Loved it!! Made learning Typescript so enjoyable. I always prefer Codecademy courses over YouTube videos because typing the syntax several times helps build my muscle memory and confidence. Being able to go at my own speed is so much better than pausing and restarting a video multiple times.

  • Informative, and the explanation has been clear and easy to follow. The exercises were also excellent and on point to put what I have learned into practice.

  • I love the hands-on experience that Codecademy provides, allowing me to implement what I learn by writing code. While I have used Coursera, Scrimba, Udemy, and Freecodecamp in the past, Codecademy offers a unique and positively impactful learning experience.
