/**

 A slider is a bar with selectable/grabbable handle. It allows users to click
 and drag horizontally to a desired value. It is used when users need to select
 a value from a predefined range of values. Sliders should always have a
 corresponding value or increment displayed within proximity of the component.

 @since 10.19.0
