A simple TypeScript IDE
TypeScript generates JavaScript through what is called a compilation step. This means that once you have written some TypeScript code, you will need to compile, or, more correctly, transpile this code, which will generate JavaScript. In order to do this compilation step, you will need a Node environment, and the TypeScript compiler itself. In this section of the chapter, we will explore the setup of a simple TypeScript IDE.
Node is a JavaScript runtime environment. Similar to how a web browser can interpret and run JavaScript code, Node can do the same thing. It is a command-line driven environment, which means that all you need is a standard command prompt in order to run JavaScript.
Installing Node is as simple as downloading the Node installer package from the Node website (https://nodejs.org) for your operating system of choice, and running it. As it is an open source package, so you can also download the source code, and compile it from scratch...
