As You could have also experienced, constructing DS components consists of contemplating extensively a few component’s api And the way it might be implemented. I’ve learnt the tricky way that components with cluttered apis and tightly coupled use instances are difficult for engineers for getting their heads all-around.
We have been utilizing a useRef as it'll return a reference that can be preserved all through render cycles. In the beginning it is ready to genuine. We only ensure it is Wrong in the event the callback is executed Using the expanded prop handed to it. For this reason The entire component Expandable.js seems like this:
