Learn what TypeScript is, why it really is a powerful Addition to JavaScript, what its Features are and how to use it! And whilst doing so, also understand what you're actually doing in your Angular 2+ Code.

This Course takes you from the very Basics and its most important Feature (Types!) to the Point where you're able to use TypeScript in any of your Projects. ReactJS Projects included!

As TypeScript is developed by Microsoft and strongly advertised used by Angular 2+ (Google), it's here to stay.

A Journey into the Future

As TypeScript code can be compiled to ES5, you'll be amazed by the many next-gen Features you can start using Today. Be it ES6 Features like Destructuring or Arrow Functions, Decorators, Generics and Interfaces or Modules - TypeScript has them all!

In this Course, we'll not stop after the Basics. You will learn about more advanced Features and also how to set up Workflows with  TypeScript. This includes a TypeScript-only Workflow as well as a Webpack Workflow.

You'll also learn that you're not limited to Angular 2+ or plain JavaScript/ TypeScript Projects. A complete Module covers how to use TypeScript with ReactJS to benefit from its Features, there, too.

Practice what you Learn

Watching Videos is a great Way to Learn. And to a lot of Students, it's the best Way. If you also want to practice the Things you learn, this Course offers you Exercises (and Solutions) in many of the Course Modules.

So much Content!

I'm not a Fan of these Courses which teach you the Basics and then leave you alone. In this Course you'll get insights into:

  • Types and how to use them

  • How the TypeScript Compiler works

  • ES6 Features in TypeScript

  • Classes in TypeScript

  • Namespaces and Modules

  • Interfaces

  • Generics

  • Decorators

  • How to integrate Third-Party JavaScript Libraries into your TypeScript Project

  • How to set up a TypeScript project with Webpack

  • Or how to set up a plain-TypeScript Workflow

  • How to use TypeScript together with ReactJS

  • How to use TypeScript together with Node/ Express

  • Real projects and use-cases!
