 * The ScaleRangeSlider widget allows the user to set a minimum and maximum scale based on named scale ranges.

 * scale range of the layer.
 *
 * The user can update the scale range by dragging thumbs across the slider to update the minScale and maxScale.
 * The user can also change the `minScale` and `maxScale` by using the dropdowns underneath the [minScaleLimit](https://developers.arcgis.com/javascript/latest/references/core/widgets/ScaleRangeSlider/#minScaleLimit)
 * and [maxScaleLimit](https://developers.arcgis.com/javascript/latest/references/core/widgets/ScaleRangeSlider/#maxScaleLimit).
