-However, when the selector is used in multiple component instances and depends on the component's props, you need to ensure that each component instance gets its own selector instance (see [here](https://github.com/reduxjs/reselect#q-can-i-share-a-selector-across-multiple-component-instances) for a more thorough explanation of why this is necessary):
