What you will learn

Compile, Test and Run TypeScript on your workstation

Use TypeScript classes and type annotations

Build and run a simple app using TypeScript


In this course, we will learn about TypeScript, the new, JavaScript inspired language by Microsoft. The introductory TypeScript course will teach the student the TypeScript basics necessary for junior workplace skills.

By taking this course you will,

- Set your PC or Mac up to develop TypeScript
- Be able to understand why TypeScript is used to build large web applications

- Use TypeScript's classes and error checking
- Create and extend TypeScript classes
- Share Code via Modules

In the first section, we will learn about what projects TypeScript is appropriate for. We will learn who makes TypeScript, and what projects use TypeScript every day.

In the second section, we will learn about using Node and NPM to install TypeScript, and how to use the command line to compile TypeScript into JavaScript. As a bonus, we'll learn a bit about TypeScript compiler errors.

In the final section, we will take a look at a few of TypeScript's many features.

We will learn about types, how they are used, what kinds are available in TypeScript, and how to make your own.

We will learn about interfaces, inheritance, and TypeScript classes. Using the module system, we will share code between TypeScript files and compile them to JavaScript.

This course includes many videos, as well as links to useful tools like the TypeScript handbook.

This course should take 3-4 hours to complete, as you may wish to pause frequently to try the many code examples provided yourself.

This code is ideal for anyone wanting a solid beginner's foundation in TypeScript, as the hands-on lecture format will ensure that any pupil has a working knowledge of the basics.

todo es excelente, lo malo es que la seccion 5 no existe y se que algunas cosas, temas de typescript para este anho 2023 ya estan "deprecated". Sin embargo si es excelente si aprendi.

An outdated and low-quality course that is just not worth the time anymore. Youtube is a better option for free content, free courses on Udemy have been underwhelming based on my experience.

Great course... Right into the basics. Excellent if you know other languages and want to get into TS.

nice course for typescript beginners, I suggest more interesting questions on quiz and code challenging maybe

Considering it's free, this is a pretty good course for an intro to TS. If, however, you already have a pretty solid dev background, I would suggest forking out some cheddar for a full course.

For an introductory class, is very well explained. Thanks to the author to give this valuable introductory information.

I give a 4 star. Capital letter pritimive types refer to non-primitive boxed objects that are almost never used in JavaScript code. It is not acceptable for teaching people the types either uppercase or lowercase.

Isn't it better to use an IDE like Visual Studio or similar? It will maybe come later on in the course?

Goes over code, doesn't explain theory in detail. Good for someone who already has some coding experience.

Very good course for beginners to learn basics of TypeScript. Instructor kept it simple and easy for beginners to understand.

Es un buen curso para entender conceptos básicos, aunque se ha quedado un poco atrás si lo que quieres es implementar typeScript en proyectos más actuales

Building an App with Typescript is missing. I'm really looking forward to it to exposed in real life application of typescript still this course is helpful.

Too little content, did not cover broader content. Only show a simple grunt setup, didn't show webpack, gulp setup.

Good intro course. As a beginner I kept getting stuck on simple logistics. Getting started: set up, installs, and file creations took longer than I expected. Deeper concept explanations: I would have also liked deeper explanations into what functions, strings, and arguments mean. I am hoping this will be covered further down in the course.

Perfect introduction to the subject. Feel I understand better what it is, how it works and what it can do. Thank you!
