Learn TypeScript
Why Learn TypeScript?
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 But as it continues to evolve, outdated code gets messy and difficult to maintain.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.
Take-Away Skills:
You will learn how to apply the JavaScript syntax you already know to TypeScript’s type system. This will help you build your own programming experience and give your code more structure. You’ll also use TypeScript’s linter to reduce compilation errors and speed up workflow.
