Solutions

Solution 1 (Click to Show/Hide)

Since you can log anything, use the console.log(); and pass in a string. The componentWillMount method should look like:

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)
