[Solved]-Is it better to pass prop to child even if I can get it from redux inside child?-Reactjs

I think this is maybe a little opinion-based. Getting it from flux store means there is a hard coupling with store lib. If you pass in the prop, you can reuse the component in another, storeless, application. I've encountered this a lot with some of the components I've made and tend towards passing props in. But again, it can make sense in some cases where the component would never see reuse anyway.

This is an opinion-based question but I've always felt and have been taught if props is only affected in the child then it should be passed down instead of using redux. If the props are used many children down and to prevent prop-drilling or needs to be referenced somewhere else that isn't directly changed by the parent then use redux.

Passing data through props makes the component a functional one or at least more functional. Such components are easier to maintain, test and reuse. It also makes it less dependent on future changes in the store structure. But, as it is often in our lives, there are no things as the only one right way. If your project contains many nested components, passing data all the way down through all layers would make code entangled and complicated.

In my practice, I always make UI components (lists, edits, grids, tables, etc.) as pure functional ones and use them inside business-logic-related components which are connected to store and perform side effects.
