Tayinlash operatorlari

Tayinlash operatorlari JavaScript o'zgaruvchilariga qiymat tayinlaydi. x = 10 va y = 5 berilganda:

Oper	Nom	Misol	Teng	Natija
=	Oddiy	x = y	x = y	x = 5
+=	Qo'shish	x += y	x = x + y	x = 15
-=	Ayirish	x -= y	x = x - y	x = 5
*=	Ko'paytirish	x *= y	x = x * y	x = 50
/=	Bo'lish	x /= y	x = x / y	x = 2
%=	Qoldiq	x %= y	x = x % y	x = 0
:	Ikki nuqta	x: 45	x = 45	x = 45

Mantiqiy tayinlash operatorlari

Oper	Nom	Misol	Natija
&&=	AND	true &&= 10	x = 10
||=	OR	false ||= 10	x = 10
??=	Nullish	null ??= 10	x = 10

---

Arifmetik operatorlar

y = 5 berilganda:

Oper	Nom	Misol	Natija
+	Qo'shish	x = y + 2	y=5, x=7
-	Ayirish	x = y - 2	y=5, x=3
*	Ko'paytirish	x = y * 2	y=5, x=10
/	Bo'lish	x = y / 2	y=5, x=2.5
**	Darajaga ko'tarish	x = y ** 2	y=5, x=25
%	Qoldiq	x = y % 2	y=5, x=1
++	Oshirish (postfiks)	x = y++	y=6, x=5
++	Oshirish (prefiks)	x = ++y	y=6, x=6
--	Kamaytirish (postfiks)	x = y--	y=4, x=5
--	Kamaytirish (prefiks)	x = --y	y=4, x=4
+	Unar plyus	x = +y	x=5
-	Unar minus	x = -y	x=-5

---

Satr operatorlari

+ va += operatorlari satrlarni birlashtirish uchun ham ishlatilishi mumkin.

Oper	Misol	t1	t2	t3
+	t3 = t1 + t2	"Good "	"Morning"	"Good Morning"
+=	t1 += t2	"Good Morning"	"Morning"

---

Taqqoslash operatorlari

x = 5 berilganda:

Oper	Nom	Taqqoslash	Qaytaradi
==	Teng	x == 8	false
==	Teng	x == 5	true
===	Qat'iy teng	x === "5"	false
===	Qat'iy teng	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

---

Mantiqiy operatorlar

x = 6 va y = 3 berilganda:

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

---

Bitli operatorlar

Bitli operatorlar 32 bitli raqamlarda ishlaydi.

Oper	Nom	Misol	Teng	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
<<	Chapga surish	x = 5 << 1	0101 << 1	1010	10
>>>	O'ngga surish	x = 5 >>> 1	0101 >>> 1	0010	2
>>	Ishorali o'ngga surish	x = 5 >> 1	0101 >> 1	0010	2
