If you are interested in learning TypeScript or Angular, one of the popular JavaScript frameworks for front-end development that uses TypeScript, and are looking for resources like books, tutorials, and courses, then you’ve come to the right place.
For those unfamiliar with TypeScript, it’s a new dynamically typed programming language from Microsoft that extends JavaScript’s programming syntax by adding new features that help with object-oriented application development, particularly the introduction of types.
As the name suggests, TypeScript is a combination of Types and JavaScript, which means you now have proper variables in your code, like a string or integer variable, and fewer type-safety-related errors to worry about.
The good thing about TypeScript is that it compiles into native JavaScript code that can be run in a browser, which means you now have better syntax for writing code. You can also take advantage of JavaScript’s ubiquity.

What is TypeScript?
Developed by Microsoft, TypeScript is an open-source programming language designed to add optional static typing to JavaScript.
It was formed to develop massive applications and then transpiling them into JavaScript. Since TypeScript is a superset of the JavaScript language, existing JavaScript programs can also be called TypeScript programs.
TypeScript is built into the 2013 and later Microsoft Visual updates as a premium programming language.
The TypeScript includes several cool features like classes, modules, and inheritance that take application development to the next level. That will appear in future JavaScript releases, making the coding and development a year longer.
TypeScript is also used in WinJS, the Windows Library for JavaScript. You can use WinJS to build things for Windows Mobile and Windows 10 OS.
It also reduces errors, which are very common in JavaScript code and difficult to debug and fix due to JavaScript’s dynamic, untyped format.
What are the requirements for learning TypeScript?
Before you start looking for TypeScript tutorials, there are a few things to remember. Since TypeScript programming is based on JavaScript, a basic understanding of JavaScript programming is a great advantage.
You don’t have to be a JavaScript expert to learn TypeScript; just a simple understanding would suffice. A basic knowledge of object-oriented programming is helpful but not essential and can come in handy when you start developing programs.
Once you’ve got the basics down, you can surf through TypeScript tutorials and start learning TypeScript.
Why Should You Learn Typescript?
In a large JavaScript project, introducing Typescript can end up providing a more robust application while still being able to be deployed anywhere a normal JavaScript application would run.
Originally it was only supported by Microsoft Visual Studio, but now it is supported by many other integrated development environments (IDE).
TypeScript also has some other features, such as B. the ability to initialize member variables in a constructor with multiple keywords in classes.
Also, TypeScript can outperform JavaScript in some cases and work faster because multiple type checks can be removed with TypeScript.
How important is TypeScript in 2024?
Most web developers learn TypeScript because of Angular 2, one of the most powerful JavaScript frameworks and libraries.
Google, which is behind Angular, chose TypeScript as the official language for Angular development, just like they chose Kotlin as the official language for Android.
By using TypeScript, you can spot many such errors at compile time. The TypeScript compiler warns you when you assign a string value to a numeric variable and vice versa.
TypeScript is especially useful for large JavaScript projects, like a project with 10,000 lines. TypeScript projects are easier to maintain than JavaScript code.
While these free courses are good to get started, they aren’t as comprehensive as some of the paid courses, and if you don’t mind paying some money for the online course, then Understanding TypeScript by Max is probably the best resource you’ll have learn TypeScript online right now.
