There are two use cases of useRef :
Retain data across multiple rerender of the component
Get reference to the DOM element / tag within the component
The above values are accessed using
.currentof the value.Thank you for that ! Much appreciated !
The short answer is that you can use
useRefwhen you want to persist some value in multiple renders of your component (similar touseState) but you don't want to re-render that component when that value changes.Tyler McGinnis has one of the best explanation on how to use useRef
