Another way to create a component besides createClass is to use ES6 class syntax. ES6 classes were introduced to offer a new way to build objects like classes. Eve refactors the SkiDayCount component as an ES6 class. We also destructure properties which isn't class specific but makes components more readable.
So instead of using create class,…we're going to use class SkiDayCount…extends React.Component.…Awesome.…So since we're using class syntax,…we also do not need the opening parentheses here…and the closing one on line 37.…Some more punctuation we can get rid of…is the comma on line 7 and the comma on line 10.…All of our methods don't need to be…separated by commas anymore when we're using class syntax.…
So let me give this a save and check it out in our browser,…and we should see that everything…is working as we expect it to,…no big changes have happened to our interface at all.…We're just using a slightly different syntax to describe it.…
