prototypal

Not many languages have prototypal inheritance, but most modern languages have first class functions these days.

To me, it's testament to just how dynamic JavaScript and prototypal inheritance are.

I'm very glad JavaScript is the language of the web. It has a combination of things I like that I don't find in many other languages:* lexical scope* first-class functions* prototypal inheritance

Thanks for putting that in your post -- JavaScript's standard prototypal inheritance as practiced with constructor functions is just a longer way to say "class".

The super idea is fairly important in the classical pattern, but it appears to be unnecessary in the prototypal and functional patterns.

However there's a big difference which is that Javascript has always had first-class functions, lexical scope, and object-oriented via prototypal inheritance.

I agree that there are many cases where prototypal inheritance is enough, though, and you shouldn't use classes by default in JavaScript.> adding types all over and maintaining them over the evolution of code is actually higherI have vastly different experience here.
