The issue I have with `const` is not your original premise, but the one you allude to here: people confuse reassignment and immutability. Because of this, they end up using const/let to "signify that they're not changing a variable," when it doesn't actually matter anyway, because they're thinking of immutability but disambiguating reassignment capability. You can usually tell who has only a superficial understanding of the language by reading how `const` and `let` are used in their code. Personally, I default to const, and use it pretty much 99.9% of the time. I use `let` in the few cases where it's actually useful to have a block-scoped variable. Ironically, this probably does a better job of "communicating" intent than the ritualistic obsession with "immutability" does, simply because you know if you're deviating from the default, there is a good reason for it.
