Understanding TypeScript from Udemy

Learn what TypeScript is, why it really is a powerful addition to JavaScript, what its features are and how to use it. Learn why TypeScript is amazing, how it improves your JavaScript code and how it helps you avoid nasty bugs and errors.

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 and used by Angular 2+ (Google) and other popular libraries, it's here to stay. Indeed, TypeScript is one of the most popular web development languages you can learn these days.

Gain an edge today and be amongst the first to really understand TypeScript.

Learn how you can use TypeScript to bring modern JS features like destructuring, arrow functions or classes to any environment and codebase - even if it does not support those features yet. Understand which types you may use and how you can build your own types. Learn how to write better code with types and with the many features offered by TypeScript.

But, in this course, we'll not stop after the basics. You will also learn about more advanced features (like decorators) 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 or plain JavaScript/ TypeScript projects. Instead, a complete module covers how you may use TypeScript with ReactJS and improve your React code with TypeScript as well.

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 more than that though. Because this course comes with plenty of exercises (and solutions, of course) in addition to all the high-quality learning videos.

So much Content.

I'm not a fan of these courses which teach you the basics and then leave you alone. Instead, in this course you'll get insights into:

Types and how to use them
How the TypeScript compiler works (and how you may configure it)
ES6 features with TypeScript
Classes in TypeScript
Namespaces and modules
Interfaces
Generics
Decorators
How to integrate Third-Party JavaScript libraries into your TypeScript projects
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.
And so much more.
