Description

Generator functions must yield at some point. Otherwise, use a normal function.

Non-Compliant Code Examples

function* foo() { return 0; }
(function* foo() { return 0; })();
var obj = { *foo() { return 0; } }
class A { *foo() { return 0; } }
function* foo() { function* bar() { yield 0; } }
function* foo() { function* bar() { return 0; } yield 0; }

Compliant Code Examples

function foo() { return 0; }
function* foo() { yield 0; }
function* foo() { }
(function* foo() { yield 0; })();
(function* foo() { })();
var obj = { *foo() { yield 0; } };
var obj = { *foo() { } };
class A { *foo() { yield 0; } };
class A { *foo() { } }
