== Why is this an issue?

The ``++for of++`` statement can only iterate over objects that have an ``++iterator++`` property.


=== Noncompliant code example

[source,javascript]
----
let obj = {};
for(let element of obj) {   // Noncompliant
  ...
}
----


=== Compliant solution

[source,javascript]
----
let array = [];
for(let element of array) {
  ...
}
----
