When it comes to Angular development, there are some things that are good to know and some things that we need to know to embark on our great journey. One of the things that is good to know is semantic versioning. This is good to know because it is the way the Angular team has chosen to deal with changes. This will hopefully make it easier to find the right solutions to future app development challenges when you go to https://angular.io/ or Stack Overflow and other sites to search for solutions. 

Another important, but sometimes painful, topic is that of project setup. It is a necessary evil that needs to be done in the beginning of a project, but getting this right early on can reduce a lot of friction as your application grows with you. Therefore, a large part of this chapter is dedicated to demystifying and enabling you as a developer to save you from future frustrations and migraines.

We will also be able to create our first application at the end of this chapter and get a feel for the anatomy of an Angular application. To sum up, here are the main themes that we will explore in this chapter.

In this chapter, we will:

• Learn about semantic versioning, why it matters, and Angular's take on it
• Discover how we set up our project using Angular CLI
• Create our first application and begin to understand the core concepts in Angular
