Just a note on immutability, I feel like this is pretty straightforward in ES6 (map, spread operator, and Object.assign) and will be more so with spread-operator for objects in ES7. Am I missing something?

I mean, you still have to THINK about whether you need to keep something immutable or not, but that's the difference between a junior developer and a more seasoned engineer, right?

This is the C++ trap - you keep piling on more features to the language and then you can answer some criticisms by saying "just use this subset". But this is not how the usage of programming languages pans out. Programmers can't agree even with themselves (=consistency) about what subset to use, or have accidents with it. And libraries / practices in that PL's culture can't rely on those conventions and subsets, so they can't really leverage the benefits. It's basically inventing your own mini-language with borders drawn in the sand and not enforced by any tooling.
