Every call to a function with a non-void return type is expected to return some value. If there is no value that's valid, you should ``++return undefined;++`` rather than using a void return (``++return;++``). Conversely, every call to a function with a void return type is expected to not return any value, even ``++undefined++``.

|
|
|

This rule raises an issue when ``++undefined++`` is returned from a void function, and when void is returned from a non-void function.

return undefined; // Noncompliant
