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 a counter, and ... well you'll get the right behavior, but your code just isn't as clean or clear.

== Noncompliant Code Example

----
const arr = [4, 3, 2, 1];

for (let i = 0; i < arr.length; i++) {  // Noncompliant
  console.log(arr[i]); 
}
----

== Compliant Solution

----
const arr = [4, 3, 2, 1];

for (let value of arr) { 
  console.log(value); 
}
