In a similar way to React, Vue focuses mainly on components. Vue is extremely flexible in how you write and register components. You can write components as plain objects, use classes and decorators, and even JSX, to name a few.
In this chapter, you will use a common form called single file components. This is very popular, especially in Vue CLI-based projects.
