> Javascript does / did the same thing (var loop variables get hoisted to the function scope, so they are available outside of the loop; add to that that `range` creates a pointer and you have a perfect storm of weird, confusing things.

let is preferred nowadays in JS and doesn’t have the weird hoisting behaviour that var does/did. JS has neither “range” nor pointers though so I’m not sure what you mean by that.
