There are two common kinds of side effects in React components: those that don’t require cleanup, and those that do.

Effects Without Cleanup

Sometimes, we want to run some additional code after React has updated the DOM. Network requests, manual DOM mutations, and logging are common examples of effects that don’t require a cleanup.

Effects with Cleanup

We might want to set up a subscription to some external data source. In that case, it is important to clean up so that we don’t introduce a memory leak!
