Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
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
|
|
|
|
[source,javascript]
|
|
----
|
|
const arr = [4, 3, 2, 1];
|
|
|
|
for (let value in arr) { // Noncompliant
|
|
console.log(value); // logs 0, 1, 2, 3
|
|
}
