== Why is this an issue?

A generator without a ``++yield++`` statement is at best confusing, and at worst a bug in your code, since the iterator produced by your code will always be empty. 


=== Noncompliant code example

[source,javascript]
----
function* myGen(a, b) {  // Noncompliant
  let answer = 0;
  answer += a * b;
}
----


=== Compliant solution

[source,javascript]
----
function* myGen(a, b) {
  let answer = 0;
  while (answer < 42) {
    answer += a * b;
    yield answer;
  }
}
----

\[~ann.campbell.2] Could you add to description smth like "It even could be a bug in your problem as you your iterator produced by this generator function is always empty"?

And I would like to remove highlighting and specific message for return, I don't think it's worth that. Are you ok?
