How it works...

When working with fields in Drupal 8, there are two steps that should be noted. When you first create a field, you are defining a base field to be saved. This configuration is a base that specifies how many values a field can support and whether any additional settings are defined by the field type. When you attach a field to a bundle, it is considered a field storage and contains configuration unique to that specific bundle. If you have the same Link field on the Article and Page content type, the label, link type, and link text settings are for each instance.

Each field type provides a method for storing and presents a specific type of data. The benefit of using these fields comes from validation and data manipulation. It also allows you to utilize HTML5 form inputs. Using HTML5 for telephone, email, and date, the authoring experience uses the tools provided by the browser instead of additional third-party libraries. This also provides a more native experience when authoring with mobile devices.
