Labeled statements in JavaScript are used in conjunction with break and continue to control flow around multiple loops. For example:

outer:
    while (cond()) {
        while (cond2()) {
            break outer;
        }
    }

While convenient in some cases, labels tend to be used only rarely and are frowned upon by some as a remedial form of flow control that is more error prone and harder to understand.

Bad Practice

label:
    while(cond()) { /* ... */ }

label:
    while(foo) {
        break label;
    }

label:
    while(bar) {
        continue label;
    }

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

label:
    {
        break label;
    }

label:
    if (a) {
        break label;
    }

Recommended

const x = {
    label: "foo"
};

while (true) {
    // code
    break;
}

while (true) {
    // code
    continue;
}
