TypeScript is a superset of the JavaScript language that introduces type safety to the language. This programming lab will introduce you to scalable, safe and maintainable JavaScript code that can be used with any modern framework including Angular2+ and ReactJS.

In this lab, you will learn the core and advanced topics related to TypeScript.
