My 2 cents
> TypeScript, which like it or not is a perfectly well-defined language.
TS these days is a broken, diverging, branch of latest ECMAScript features,
IMO.
```js
class List extends Array { }
console.log(new List instanceof List);
// false .. seriously
```
Try it yourself. [1]
You can also argue that type, enum, interface, and private are also not
aligned with ECMAScript so as much as "well-defined language" as it is, it
shouldn't compromise any future development of an already "well-defined
language" too which is JavaScript.
