Ha kerülendő a ciklusokban a break; utasítás akkor mit használjunk helyette?

Pl ehelyett:

for (let i = 0; i < array1.length; ++i) {

let includes = false;

for (let j = 0; j < union.length; ++j) {

if (array1[i] == union[j]) {

includes = true;

break;

}

}

if (!includes) {

union.push(array1[i]);

}

}

Ezt?

for (let i = 0; i < array1.length; ++i) {

let includes = false;

for (let j = 0; j < union.length && !includes; ++j) {

if (array1[i] == union[j]) {

includes = true;

}

}

if (!includes) {

union.push(array1[i]);

}

}
