E0024: const/let/var with no bindings

const, let, or var statements need to declare at least one variable. It is an error to declare nothing:

const friends = ["strager"];
for (let  of friends) {

To fix this error, add a variable name:

var bestFriend;
const friends = ["strager"];
for (let friend of friends) {
  bestFriend = friend;

Introduced in quick-lint-js version 0.2.0.
