If you have an iterable, such as an array, set, or list, your best option for looping through its values is the ``++for of++`` syntax. Use ``++for in++`` and you'll iterate the properties, rather than the values.
== Noncompliant Code Example
----
const arr = [4, 3, 2, 1];
for (let value in arr) { // Noncompliant
console.log(value); // logs 0, 1, 2, 3
}
== Compliant Solution
for (let value of arr) {
console.log(value);
