# Explain about types of side effects in React
component.

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!
