Summary

That's it! Your journey to the world of Angular has just begun. Let's recap the features that you have learned so far. We looked at semantic versioning and how modern JavaScript frameworks such as Angular use it. We looked over the brief history of the Angular framework and learned how semantic versioning helps the Angular team to deliver up-to-date high-quality features.

We saw how to set up our working space and where to go to find the tools that we need to bring TypeScript into the game and use the Angular framework in our projects, going through the role of each tool in our application. We introduced the Angular CLI tool, the Swiss Army knife for Angular, that automates specific development tasks, and we used some of the most common commands to scaffold our very first Angular application. We had a glimpse of the structure of an Angular component and learned how to interact with it.

Our first application gave us a basic understanding of how Angular works internally to render our app on a web page. We embarked on our journey, starting with the main HTML file of an Angular application. We saw how Angular parses that file and starts searching the component tree to match HTML elements with component selectors and templates. We learned that components that share similar functionality are grouped into modules and looked at how Angular bootstraps the very first module of the application.

Finally, we met some of the most popular IDEs and learned how they can empower you as a software developer. There are many choices for editors, some of which we have chosen to cover in more detail, such as VS Code. There are also many plugins and snippets that save quite a few keystrokes. At the end of the day, your focus and energy should be spent on solving the problem and structuring your solution, not making your fingers tired. We encourage you to learn more about your editor and its possibilities because this will make you faster and more efficient.

In the next chapter, you will learn all about TypeScript, everything from the basics to the professional level. The chapter will cover what problems can be solved by introducing types, but also the language construct itself. TypeScript, as a superset of JavaScript, contains a lot of powerful concepts and marries well with the Angular framework, as you are about to discover.
