TypeScript Crash Course from Udemy

Course description:

The course will show you the most important features of TypeScript. In the beginning, we will install and set up the required software together. After that, we will start with the basics and work our way up to classes and inheritance. You are also welcome to watch the public videos of the course to get a taste of it.

What is TypeScript?

If you haven’t heard of TypeScript yet, it’s a language that builds on JavaScript by adding syntax for static types. Tools like the TypeScript compiler just erase those types, leaving you with clean readable JavaScript that you can run anywhere; but those types are there to be type-checked. Types make your intentions explicit, and tools can read and understand them to catch errors before you even run your code. By checking your types, TypeScript can catch errors like typos, logic errors, and more. Beyond catching errors, TypeScript also uses types to power editor toolings like accurate code completion, go-to-definition, and renaming.

The course has the following topics

Installation of TypeScript, NodeJS, and VSCode
Type Annotations for Number, String, Boolean, Arrays, Tuples, etc.
Functions, Interfaces, and Classes
Inheritance and Abstract Classes
Importing/exporting from Modules
Utility types, keyof, instanceof, and type guards

Become a professional today, in the technology of tomorrow.

See you in class.
