title: Use the Lifecycle Method componentWillMount
---
## Use the Lifecycle Method componentWillMount
The challenge is a basic introduction to React's LifeCycle components.
These methods are also called Lifecycle Hooks.
### Hint 1
Log something to the console in the ```react componentWillMount ``` method.
### Hint 2
The `` console.log(); `` statement is used to log to the browser console.
### Solution
Since you can log anything, use the ``` console.log(); ``` and pass in a string. The ``` componentWillMount ``` method should look like:
```javascript
componentWillMount() {
console.log('Component being mounted');
}
```
##### Note: The ``` componentWillMount ``` Lifecycle method has been deprecated as of version 17, and does not work on later versions. [(Source)](https://reactjs.org/docs/react-component.html)
