JS operatorlari

Operatorlar bo‘yicha to‘liq ma’lumotnoma

2025 yil iyul oyida qayta ko‘rib chiqilgan

Turi	Umumiy qo‘llanilishi	Misol
Topshiriq	O‘zgaruvchilarga qiymat beradi	x = 5
Arithmetic	Performs arithmetic between variables	x = y + 2
Comparison	Compares variables	x > 8
Logical	O‘zgaruvchilar orasidagi mantiqni belgilaydi	(x>0 \|\| x>0)
Bitwise	32 bitli sonlar ustida bitli amallarni bajaradi	x = 5 & 1
Misc	Miscellaneous operators	void(0)

JavaScript tayinlash operatorlari

Tayinlash operatorlari JavaScript o‘zgaruvchilariga qiymatlarni tayinlaydi.

X = 10 va y = 5 ekanligini hisobga olsak, quyidagi jadvalda tayinlash operatorlari tushuntiriladi:

Oper	Name / Link	Misol	Ekvivalenti	Natija
=	Simple	x = y	x = y	x = 5
+=	Add	x += y	x = x + y	x = 15
-=	Subtract	x -= y	x = x - y	x = 5
*=	Multiply	x *= y	x = x * y	x = 50
/=	Divide	x /= y	x = x / y	x = 2
%=	Remainder	x %= y	x = x % y	x = 0
:	Colon	x: 45	x = 45	x = 45

Mantiqiy tayinlash operatorlari

Oper	Name / Link	Misol	Natija
&&=	AND	true &&= 10	x = 10
\|\|=	OR	false \|\|= 10	x = 10
??=	Nullish	null ??= 10	x = 10

JavaScript arifmetik operatorlari

Arifmetik operatorlar o‘zgaruvchilar va/yoki qiymatlar o‘rtasida arifmetikani bajarish uchun ishlatiladi.

y = 5 ekanligini hisobga olsak, quyidagi jadval arifmetik operatorlarni tushuntiradi:

Oper	Name / Link	Misol	Natijalar
+	Addition	x = y + 2	y=5, x=7
-	Subtraction	x = y - 2	y=5, x=3
*	Multiplication	x=y*2	y=5, x=10
/	Division	x = y / 2	y=5, x=2.5
**	Exponentiation	x = y ** 2	y=5, x=25
%	Remainder	x = y % 2	y=5, x=1
++	Increment	x = y++	y=6, x=5
++	Increment	x = ++y	y=6, x=6
--	Decrement	x = y--	y=4, x=5
--	Decrement	x = --y	y=4, x=4
+	Unary Plus	x= +y	x=5
-	Unary Negation	x= -y	x=-5

JavaScript string operatorlari

+ va += operatorlari stringlarni birlashtirish (qo‘shish) uchun ham ishlatilishi mumkin.

t1 = "Yaxshi", t2 = "Tong" va t3 = "" ekanligini hisobga olsak, quyidagi jadval operatorlarni tushuntiradi:

Oper	Misol	t1	t2	t3	Try it
+	t3 = t1 + t2	"Good "	"Morning"	"Good Morning"	Try it »
+=	t1 += t2	"Good Morning"	"Morning"		Try it »

JavaScript solishtirish operatorlari

Taqqoslash operatorlari mantiqiy operatorlarda o‘zgaruvchilar yoki qiymatlar orasidagi tenglik yoki farqni aniqlash uchun ishlatiladi.

X = 5 ekanligini hisobga olsak, quyidagi jadval taqqoslash operatorlarini tushuntiradi:

Oper	Name / Link	Comparing	Qaytaradi
==	Teng	x == 8	false
==	Teng	x == 5	true
===	Strict Equal	x === "5"	false
===	Strict Equal	x === 5	true
!=	Teng emas	x != 8	true
!==	Qat’iy teng emas	x !== "5"	true
!==	Qat’iy teng emas	x !== 5	false
>	Katta	x > 8	false
<	Kichik	x < 8	true
>=	Katta yoki teng	x >= 8	false
<=	Kichik yoki teng	x <= 8	true

JavaScript mantiqiy operatorlari

Mantiqiy operatorlar o‘zgaruvchilar yoki qiymatlar orasidagi mantiqni aniqlash uchun ishlatiladi.

X = 6 va y = 3 ekanligini hisobga olsak, quyidagi jadval mantiqiy operatorlarni tushuntiradi:

Oper	Name / Link	Misol
&&	AND	(x < 10 && y > 1)
\|\|	OR	(x === 5 \|\| y === 5)
!	NOT	!(x === y)
??	Nullish Coalescing	x ?? y

JavaScript bitli operatorlari

Bit operatorlari 32 bitli raqamlarda ishlaydi. Operatsiyadagi har qanday raqamli operand 32 bitli raqamga aylantiriladi. Natija yana JavaScript raqamiga aylantiriladi.

Oper	Name	Misol	Ekvivalenti	Natija	Dec
&	AND	x = 5 & 1	0101 & 0001	0001	1
\|	OR	x = 5 \| 1	0101 \| 0001	0101	5
~	NOT	x = ~ 5	~0101	1010	10
^	XOR	x = 5 ^ 1	0101 ^ 0001	0100	4
<<	Left Shift	x = 5 << 1	0101 << 1	1010	10
>>>	Right Shift	x = 5 >>> 1	0101 >>> 1	0010	2
>>	Signed Right	x = 5 >> 1	0101 >> 1	0010	2
