In the [previous episode](https://watch-learn.com/react-2020/lifecycle-methods) we learned about lifecycle methods in Reacts class components. Since we can't use those methods in functional components, we have to use React Hooks. And one hook that is going to give us similar effects to lifecycle hooks is `useEffect`.

However, you will hear me repeat several times in the video that `useEffect` is not the same thing as something like `componentDidMount`. And that is why I urge you to read an [article by Dan Abramov](https://overreacted.io/a-complete-guide-to-useeffect/) called "A Complete Guide To useEffect" talking about `useEffect` in much more depth. Go, read it!

In this episode we are going to take a look at an useEffect Hook for React and how it approximates to some lifecycle methods.

useEffect Hook

There are a few lifecycle methods that you can use in React. These methods will fire in certain parts of the lifecycle of your component. In this episode we are going to cover the most used methods, namely: `componentDidMOunt`, `componentDidUpdate` and `componentWillUnmount` and as an extra we are also going to take a look at the `getSnapshotBeforeUpdate` which ties in with `componentDidUpdate` method. As you will see.

In this episode we are going to go through the most used React lifecycle methods.
