Summary

We introduced this chapter by providing a short introduction to TypeScript by focusing on the basic types and language abstractions. We compared its relationship to JavaScript and followed some steps to convert a program written in JavaScript into TypeScript.

We then reviewed the libraries that we will use throughout this book and how they will help us develop scalable applications. We explored the tsconfig file and its options.

Using the VSCode editor, we learned how to run and debug code and this book's examples. We then performed some refactorings, which helped us refine the code even better. Finally, we introduced UML and class diagrams, which are used as a traditional way of modeling design patterns or abstractions.

By applying what you have learned so far, you can start developing basic TypeScript projects that will help you become familiar with the language. Learning how to add VSCode tasks and launch configurations can help you master this programming editor and be more productive. Understanding UML diagrams helps you use a standardized way to document computer systems and models.

In the next chapter, we will delve deeper into the TypeScript type system and learn about more advanced types.
