== Why is this an issue?

The ``++yield++`` keyword is used in a generator function to return an ``++IteratorResult++`` to the caller. It has no other purpose, and if found outside such a function will raise a ``++ReferenceError++`` because it is then treated as an identifier.


=== Noncompliant code example

[source,javascript]
----
function foo() { 
  for (var i = 0; i < 5; i++) { 
    yield i * 2; 
  } 
}
----


=== Compliant solution

[source,javascript]
----
function * foo() { 
  for (var i = 0; i < 5; i++) { 
    yield i * 2; 
  } 
}
----
