Tavsif
break operatori switch blokidan yoki sikldan chiqaradi.
switch ichida u switch blokidan chiqaradi. Bu switch ichidagi qolgan kodning bajarilishini to‘xtatadi.
Siklda esa u sikldan chiqaradi va sikldan keyingi kodni (agar bo‘lsa) bajarishda davom etadi.
Yorliqlardan (label) foydalanish
break operatori istalgan JavaScript kod blokidan chiqish uchun yorliq (label) havolasidan foydalanishi mumkin (quyidagi "Ko‘proq misollar" bo‘limiga qarang).
Yorliqsiz break faqat sikl yoki switch ichida ishlatilishi mumkin.
Sintaksis
break;
Ixtiyoriy yorliq havolasidan foydalanish:
break labelname;

Biror case rost bo‘lganda switch blokidan chiqing:

switch (new Date().getDay()) {
case 0:
day = "Sunday";
break;
case 1:
day = "Monday";
break;
case 2:
day = "Tuesday";
break;
case 3:
day = "Wednesday";
break;
case 4:
day = "Thursday";
break;

Ro‘yxat blokidan chiqing:
let text = "";
const cars = ["BMW", "Volvo", "Saab", "Ford"];
list: {
text += cars[0] + "<br>";
text += cars[1] + "<br>";
text += cars[2] + "<br>";
break list;
text += cars[3] + "<br>";

Misol
Ichma-ich sikldan chiqing:
// The first for loop is labeled "Loop1"
Loop1:
for (let i = 0; i < 3; i++) {
// The second for loop is labeled "Loop2"
Loop2:
for (let i = 10; i < 15; i++) {
if (i === 12) break Loop1;
}
}
