I'm not a academic nor hobbyist but work professionally with JavaScript for more than 10 years.

I'm also "against" the constant syntactic sugar that gets added with little to no benefits, just leading to JavaScript having a large syntax.

Why introduce "classes" which are just sugar on top of existing syntax? Many examples just like this, where sometimes it feels like JavaScript has changes just to have changes.

Although I'm not gonna complain too much, many of the new features are more than just syntactic sugar and makes my life a lot easier. I just wish they were slightly more conservative I guess.
