The thing is, you can't really avoid them. It's an important part of the language, and not understanding my bring you pain.

In mid-late-2000s when the first idea of adding classes to the syntax came up, even Microsoft eventually said: nah, it's a bad idea. It's grafting incompatible concepts onto a language that doesn't need them.

And then Google in their "wisdom" went and forced classes onto the language. Take a guess why you need this for methods to work the way you expect them:

   class Logger {
     constructor () {
       this.method = this.method.bind(this);
     }

     method (some, params) {
       this.do_stuff()
     }

     /// ...
   }
