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