Function useMeasure

useMeasure<E extends Element = Element>(): [MeasureRef<E>, MeasureRect]
Tracks the content-box size of an element.
Type Parameters
- E extends Element = Element
Returns [MeasureRef<E>, MeasureRect]
Remarks
Returns all zeros until the ref is attached; the element is measured as soon as it is attached (before paint) and again whenever a ResizeObserver reports a change. The returned rect keeps its identity while the size is unchanged. Where ResizeObserver is unavailable the rect stays zero.

Changes from CSS transforms are not observed; see useAnimatedMeasure.
Example
```
const [refMeasure, { width }] = useMeasure<HTMLDivElement>();
return <div ref={refMeasure}>{width}px wide</div>;
```
