JavaScript Building Applications with React and Redux Modularizing the React Scoreboard Application Cleaning up the Scoreboard Container Component

I'm confused by some of the syntax changes that were made when modularizing, specifically in Scoreboard.js

After modularizing the app, the key value properties of the scoreboard component were changed to just regular declarations of variables and functions. So in this methodology the scoreboard component is no longer an object? like onScoreChange went from being onScoreChange: to onScoreChange = (index, delta) =>.

I understand ES6. But does it always have to be like this when modularizing? Can you keep it as an object if export is called separately at the bottom?

You don't have to. For example you don't have to use :

export default class Scoreboard extends Component

You can use the React.createClass syntax.

It's just that the class syntax may look better visibility, and it works. However, I think React.createClass is deprecated in newer versions of React, so the class syntax is a better option.
