Massivni nusxalash va saralash

Bizda arr massivi mavjud. Biz uning tartiblangan nusxasini olishni xohlaymiz, ammo arr ni o’zgartirmasdan.

Bunday nusxani qaytaradigan copySorted(arr) funktsiyasini yarating.

let arr = ["HTML", "JavaScript", "CSS"];

let sorted = copySorted(arr);

alert(sorted); // CSS, HTML, JavaScript
alert(arr); // HTML, JavaScript, CSS (hech qanday o'zgarish yo'q)

Nusxasini olish va undagi tartibni bajarish uchun slice() dan foydalanishimiz mumkin:

function copySorted(arr) {
  return arr.slice().sort();
}

let arr = ["HTML", "JavaScript", "CSS"];

let sorted = copySorted(arr);

alert( sorted );
alert( arr );
