JS for loop label

let num = 0;
for (let i = 0; i < 10; i ++) {
    for (let j = 0; j < 10; j ++) {
        if (i === 5 && j === 5) {
            break;
        }
        a ++ ;
    }
}
console.log(num); // 95

Conditions are satisfied break out of that cycle of internal

If all conditions are met to get out of the cycle of how to do?

let num = 0;
out:
for (let i = 0; i < 10; i ++) {
    for (let j = 0; j < 10; j ++) {
        if (i === 5 && j === 5) {
            break out;
        }
        a ++ ;
    }
}
console.log(num); // 55
for loop out of label point to the current cycle block 
out BREAK out when the code block is pointed out
