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.
function* myGen(a, b) { // Noncompliant
let answer = 0;
answer += a * b;
}
function* myGen(a, b) {
let answer = 0;
while (answer < 42) {
answer += a * b;
yield answer;
}
}
