I'm actually a fan of the class syntax, and use it regularly.

>no need to even type function for methods

However, to be fair, you can do this with object method shorthand now:

    const deepThought = {
              theAnswer: 42,
              tellTheAnswer() {
                  return `The answer to life, the universe, and everything is ${this.theAnswer}`;
              },
          };

    deepThought.tellTheAnswer(); // => 'The answer to life, the universe, and everything is 42.'

Which is also quite elegant. I think they both have their places depending on the program. I think it depends on readability needs at the time, and whether an instance is better than just a container in that circumstance.
