Those interested in how prototypes and classical inheritance relate (and don't) may be interested in work I did on GNU ease.js, which works with ECMAScript 3+.

Those interested in how prototypes and classical inheritance relate (and don't) may be interested in work I did on GNU ease.js, which works with ECMAScript 3+. I have since extended it to support Scala-like traits. https://www.gnu.org/software/easejs/manual/easejs.html#Implementation-Details https://www.gnu.org/software/easejs/manual/easejs.html#Imple... I also wrote a paper on some of the concepts: https://mikegerwitz.com/papers/coope/coope.pdf https://mikegerwitz.com/papers/coope/coope.pdf The `class' keyword in JS still leaves much to be desired; it's just syntatic sugar around the prototype model. There's nothing wrong with that model---it's just important to understand how it differs from what OOP developers traditionally expect.
