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.
myLabel: if (i % 2 == 0) { // Noncompliant if (i == 12) { console.log("12"); break myLabel; } console.log("Odd number, but not 12"); }
myLabel: for (i = 0; i < 10; i++) { // Compliant console.log("Loop"); break myLabel; }
