Description
TypeScript was selected as a main language for the Angular framework, and nowadays it is widely used for React development and for building any enterprise-level Frontend applications.
It gives you the possibility to use the syntax which is closer to languages like Java or C#, and allows you to write more accurate, convenient, and easy to maintain code.
