There are some things that we need to learn before going deep into the components and rewrite our applications using them. In this section, we will cover things such as handling data and el properties inside a component, component templates, scope, and preprocessors.
In our previous example, we created a Vue component with a template written as a string. It's actually easy and nice because we have everything we need inside our component.
