- /* React components have several special methods that provide opportunities to perform actions at specific points in the
- lifecycle of a component. These are called lifecycle methods, or lifecycle hooks, and allow you to catch components at
- certain points in time. This can be before they are rendered, before they update, before they receive props, before they
- unmount, and so on. Here is a list of some of the main lifecycle methods:
- componentWillMount()
- componentDidMount()
- componentWillReceiveProps()
- shouldComponentUpdate()
- componentWillUpdate()
- componentDidUpdate()
- componentWillUnmount()
- The next several lessons will cover some of the basic use cases for these lifecycle methods.
- The componentWillMount() method is called before the render() method when a component is being mounted to the DOM.
- Log something to the console within componentWillMount() - you may want to have your browser console open to see the output.

- class MyComponent extends React.Component {

- // change code below this line
- console.log(" The componentWillMount() method is called before the render() method when a component is being mounted to the DOM")
- // change code above this line

- render() {
- return <div />
