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 But as it continues to evolve, outdated code gets messy and difficult to maintain.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