In this Best Courses Guide (BCG) I’ve selected the best online courses, resources, and tutorials to learn TypeScript for beginners and also intermediate programmers. Most of the courses are free.

TypeScript has made a huge splash in the web development industry. It is being used to develop all sorts of amateur and professional projects and websites by notable companies such as Slack and medium.com. And with Microsoft fully backing the TypeScript language, it doesn’t seem like TypeScript will go away anytime soon. Rather, it will only increase in popularity, as according to The State of JS 2024 survey, 92% of JavaScript developers use TypeScript.

What is TypeScript?

TypeScript is a strongly-typed programming language created by Microsoft to aid the development of large-scale JavaScript applications. It is a superset of JavaScript and transpiles to clean readable JS.

JavaScript is a dynamically-typed language. This means that it can get difficult to track the properties of objects in a large codebase, along with being unable to take advantage of intelligent code inspections. TypeScript solves these issues by forcing the programmer to declare types, saving the programmer a lot of trouble down the road.

TypeScript is also, in a lot of ways, modern. Not only do you have a flexible type system, you also have access to interfaces, async/await, and much more. To top it all off, TypeScript is compatible with all existing JavaScript packages! With these reasons in mind, it’s easy to see why TypeScript is admired by almost 70% of developers according to the StackOverflow Developer Survey.

Best Courses Guides Methodology

I built this article following the now tried-and-tested methodology used in previous Best Courses Guides (you can find them all here). It involves a three-step process:

1. Research: I started by leveraging Class Central’s database with 250K online courses and 250K reviews. Then, I made a preliminary selection of 1,100+ Typescript courses by rating, reviews, and bookmarks.
2. Evaluate: I read through reviews on Class Central, Reddit, and course providers to understand what other learners thought about each course and combined it with my own experience as a learner.
3. Select: Well-made courses were picked if they presented valuable and engaging content and fit in a set of criteria such as: comprehensive curriculum, price, release date, ratings and enrollments.

Fabio and Pat revised later versions of this article.
