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 But as it continues to evolve, outdated code gets messy and difficult to maintain.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.

  • The explanations were great, the examples were easy to follow, and the tasks were split up so they were easily digestible. Would highly recommend to anyone wanting to learn TypeScript basics!

  • 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.
