#Rule Details

This rule disallows labels that are only used on loops or switch statements that have no nested breakable statement — in those cases a bare break / continue already refers to the directly-enclosing loop or switch, so the label adds no information and can confuse readers who expect labels to control deeper nesting.

Examples of incorrect code for this rule:

A: while (a) {
    break A;
}

B: for (let i = 0; i < 10; ++i) {
    break B;
}

C: switch (a) {
    case 0:
        break C;
}

Examples of correct code for this rule:

while (a) {
    break;
}

A: {
    break A;
}

B: while (a) {
    while (b) {
        break B;
    }
}

C: switch (a) {
    case 0:
        while (b) {
            break C;
        }
}
