The idea behind Lightning base components is to accelerate development by providing out-of-the-box components that have built-in design patterns, found in the Salesforce Lightning Design System (https://www.Lightningdesignsystem.com/). The components also have JavaScript functions built in, and include attributes to ease customization. These components may not provide all of the flexibility that we need, and they may not fit for all business requirements, but they can be used for most common use cases. The library is rich, and is getting better with every release. You will find components such as carousel, tree, datatable, input forms, and more.

In this section, we will briefly discuss a few of the important components, with examples. For a comprehensive listing, always refer to the Salesforce release notes and the component library. Note that these components have the Lightning namespace.
