Disallows using an argument name more than once in a function signature.
If you supply multiple arguments of the same name to a function, the last instance will shadow the preceding one(s). This is most likely an unintentional typo.
Invalid:
function withDupes(a, b, a) {
console.log("I'm the value of the second a:", a);
}
Valid:
function withoutDupes(a, b, c) {
console.log("I'm the value of the first (and only) a:", a);
}
