One of the new features in ES6 is the addition of the `class` keyword.
To be clear, CLASSES DO NOT REALLY EXIST in JavaScript. All the Class functionality is still just a syntactic wrapper around Objects and the JavaScript Prototype chain.
However, that doesn't mean you can't use them to write your code.

Hey Steve. Just wanted to let you know that your videos helped me out tackling a frontend education. I had my first job interview recently and I could answer all the technical questions, so I wanted to thank you for making these videos for FREE and I can't wait to check out your videos on React also. I'm switching career from English teacher to web developer and I just wanted to thank you so much.

Still a long way to go, but I figured it's rare to see a comment that's not about being a beginner (not that there's any problem with it). As a teacher I love when students are taking that knowledge somewhere and you actually made a difference.

And you Sir, actually did. Thank you

Rewatched again to refresh my memory, outstanding intro👏.
I hate classes(because they're too verbose, not as eloquent as functions). Try to omit them whenever I can. But sometimes they're necessary, I didn't find another way to draw bullets in a canvas shooting game.

i just don't get it with static methods. like if i want to use a constructor and static methods, how will i use the class, you know what i mean ? like do i use new Car() or just Car ? if i use Car, i guess constructor isn't calling, right ?

Hi Steve, why did you in the end use Car.accelerate() and not ferrari.accelerate()? Isn’t it the point that you have the ferrari inherit the class methods of Car and then use it? Thank you for the explaining btw.
