TypeScript

Finally, as obvious as it may be, yes, you will also need to install TypeScript.

If you install VS Code, Visual Studio, WebStorm, IntelliJ, or another IDE that supports TypeScript natively, then you already have TypeScript on your machine. Anyway, you'll still need to install it separately from the IDE for reasons that we'll cover in the next sections.

Regardless of how you install it, once TypeScript is installed on your machine, you will get access to the TypeScript compiler, which is called tsc. TypeScript is distributed as an npm package and it can easily be installed using npm. As you will soon see, there are different ways to install npm packages. Some make more or less sense depending on the use case and some others may cause actual issues for development teams.
