Rendering of component on unused prop updation

I have been wondering if a component gets rendered again if the a prop is updated and its not being used in render method. I am using Redux and some unnecessary props have been added to the component with mapStateToProps of connect method. I know I should remove the prop if they are not used, but before I wanted to be sure if it makes any difference.

Solution

  • Yes, on default it will/should rerender.
