Any statement or block of statements can be identified by a label, but those labels should be used only on ``++while++``, ``++do-while++``, ``++for++`` and ``++switch++`` statements. Using labels in any other context leads to unstructured, confusing code. 

== Noncompliant Code Example

----
myLabel: if (i % 2 == 0) {  // Noncompliant
  if (i == 12) {
    console.log("12");
    break myLabel;
  }
  console.log("Odd number, but not 12");
}
----

== Compliant Solution

----
myLabel: for (i = 0; i < 10; i++) {   // Compliant
  console.log("Loop");
  break myLabel;
}
