A comment on JavaScript variables: var and let and const. Parent comment

I like that Swift has var and let. Having the first letter be different means less typing with autocompletion.

I suppose when I get to use voice recognition for coding, there will also be less confusion.

Generally speaking most languages treat `let` as constant/immutable, and the real shame is that JS did not. It's understandable why (they needed a block-scoped `var`), but unfortunate nonetheless.
