JavaScriptda Arraylarni saralash usullari.!!

Alifbo tartibida saralash.!
Array sort() Array reverse() Array toSorted() Array toReversed()

Raqamli saralash.!
Numeric Sort Random Sort Math.min() Math.max() Home made Min() Home made Max()

1.sort()
Ushbu metod Array elementlarini alifbo tartibida saralaydi, asl arrayga ta’sir qiladi.!

const fruits = ['grapes','lemon','nut','strawberry','apple','banana'];
console.log(fruits);
//natija - [' grapesgrapes', 'lemon', 'nut','strawberry', 'apple', 'banana'] const fruits_sort = fruits.sort();
console.log(fruits_sort);
//natija - ['apple', 'banana', 'grapes', 'lemon', 'nut', 'strawberry'] console.log(fruits);
//natija - ['apple', 'banana', 'grapes', 'lemon', 'nut', 'strawberry', 'strawberry']

2.reverse()
Ushbu metod Array elementlarini teskari tartibda joylashtiradi, asl Arrayga tasir qiladi.!

const fruits = ['grapes','lemon','nut','strawberry','apple','banana'];
console.log(fruits);
//natija - [' grapesgrapes', 'lemon', 'nut', 'strawberry', 'apple', 'banana'] const fruits_reverse = fruits.reverse();
console.log(fruits_reverse);
//natija - ['banana', 'apple','strawberry', 'nut', 'lemon', 'grapes'] console.log(fruits);
//natija - ['banana', 'apple','strawberry', 'nut', 'lemon', 'grapes']

3.toSorted()
Ushbu metd ES2023 da qo’shilgan bo’lib sort() metodi kabi ishlaydi. Ammo ular orasida bitta farq bor: toSorted() sort() dan farq qilgan xolda aasl Arrayga ta’sir qilmaydi.!

const fruits = ['grapes','lemon','nut','strawberry','apple','banana'];
console.log(fruits);
//natija - [' grapesgrapes', 'lemon', 'nut', 'strawberry', 'apple', 'banana'] const fruits_toSorted = fruits.toSorted();
console.log(fruits_toSorted);
//natija - ['apple', 'banana', 'grapes', 'lemon', 'nut', 'strawberry',] console.log(fruits);
//natija - [' grapesgrapes', 'lemon', 'nut', 'strawberry', 'apple', 'banana']

Enter fullscreen mode
Exit fullscreen mode

4.toReversed()
Ushbu metod ES2023 da qo’shilgan bo’lib reverse() metodi kabi ishlaydi, ammo ular orasida bitta farq bor toReversed() metodi reverse() metodidan farq qilgan xolda asl Arrayga ta’sir qilmaydi.!

const fruits = ['grapes','lemon','nut','strawberry','apple','banana'];
console.log(fruits);
//natija - ['grapes', 'lemon', 'nut', 'strawberry', 'apple', 'banana'] const fruits_toReversed = fruits.toReversed();
console.log(fruits_toReversed);
//natija - ['banana', 'apple', 'strawberry', 'nut', 'lemon', 'grapes'] console.log(fruits);
//natija - ['grapes', 'lemon', 'nut', 'strawberry', 'apple', 'banana']

Raqamli saralash.!

5.sort()

Ushbu metod satrlarli Array elementlarini saralashda qulay usul hisoblanadi, raqamlarni saralashda hatoliklarga olibkeladi ammo ushbu metoddan va funciyadan foydalanib raqamlarni saralashimizham mumkin.!

const numbers = [3,24,16,12,20,120,100,7];
console.log(numbers);
//natija - [3, 24, 16, 12, 20, 120, 100, 7] const numbers_sort = numbers.sort();
console.log(numbers_sort);
//natija - [100, 12, 120, 16, 20, 24, 3, 7] console.log(numbers);
//natija - [100, 12, 120, 16, 20, 24, 3, 7] const numbersFunc = numbers.sort( function numbersF(x,y){return x-y}
); console.log(numbersFunc);
//natija - [3, 7, 12, 16, 20, 24, 100, 120]

Array elementlarini kamayish usulida saralash.

const numbersFunc = numbers.sort( function numbersF(x,y){return y-x}
); console.log(numbersFunc);
//natija - [3, 7, 12, 16, 20, 24, 100, 120]

6.Random Sort
Ushbu metod array elementlarini tasodifiy usulda saralaydi.!

const numbers = [3,24,16,12,20,120,100,7];
console.log(numbers);
//natija - [3, 24, 16, 12, 20, 120, 100, 7] const numbers_random = numbers.sort( function mathRandom(){return 0.5 - Math.random()}
) console.log(numbers_random);
//natija - [7, 100, 16, 12, 120, 20, 24, 3]

7.Min(), Max()
Sort() yordamida min yoki max qiymatni topish usuli.!

//MIN-
const numbers = [3,24,16,12,20,120,100,7];
console.log(numbers);
//natija - [3, 24, 16, 12, 20, 120, 100, 7] const number_min = numbers.sort( function(a,b){ return a-b; }
); console.log(numbers[0]);
//natija - 3 //MAX-
const numbers = [3,24,16,12,20,120,100,7];
console.log(numbers);
//natija - [3, 24, 16, 12, 20, 120, 100, 7] const number_min = numbers.sort( function(a,b){ return b-a; }
