Replace a bunch of `let` with `const`

According to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const

> Many style guides (including MDN's) recommend using const over let whenever a
variable is not reassigned in its scope. This makes the intent clear that a
variable's type (or value, in the case of a primitive) can never change.
