Now that we are familiar with Lightning Experience, the Lightning Component framework architecture, and the Lightning Design System, we are ready to dive deep and explore the Lightning Component framework further.

Let's also address the question of why we should invest time in learning this framework. The primary reason for learning this framework is that to customize Lightning Experience or Lightning pages, we will need to build custom Lightning Components. Also, as we will see later, the Lightning Component framework can be used to build Salesforce communities. It can also be used to build chatter extensions, Salesforce extensions for Outlook, and extensions in other Salesforce products.

In the next chapter, we will explore how to use Salesforce DX and an IDE to set up our development workflow for source-driven development.
