This was a very quick introduction to TypeScript. The TypeScript documentation is a great place for learning all the other functionalities and to dive into the details of the topics we quickly covered in this chapter; it can be found at https://www.typescriptlang.org/docs/home.html.
TypeScript also has an online playground (similar to Babel) that we can use to play with some code examples, at https://www.typescriptlang.org/play/index.html.
