That % syntax is just completely unlike anything else I have seen in JS.
As a multi paradigm language, JS typically suffers from whatever programming style is on trend when these features are implemented. We are apparently on the other side of the pendulum now, but I can’t remember the last time I worked with a class and felt like that was right either.
We said the same things when arrow functions got introduced using an outlandishly un-javascripty syntax, as well as when templating strings got introduced using symbols that were the domain of LaTeX. Now they're "just what JS looks like" to both old and new JS devs.
Look past the syntax, because you'll master it quickly enough and 2 years down the line forget it was ever not part of the language: does the actual functionality it introduces improve on what we can do and how we write and understand code or not?
Working with something that uses an ES3-like level of the JS language, it's actually painful not having some of the conveniences added in the past decade+.

Perhaps they are just jealous of the C++ committee. How many lambdas have they proposed and added to the language? At least 3: the C one, the Java one and now the Rust one.
