JavaScript Operators

Operators in JavaScript are special symbols or keywords that are used to perform operations on operands (values and variables). They are essential in every JavaScript program to perform mathematical, logical, or assignment operations.

1. Arithmetic Operators

These operators are used to perform arithmetic calculations such as addition, subtraction, multiplication, etc.

Operator	Description	Example	Output
+	Addition	let x = 5 + 3;	8
-	Subtraction	let x = 5 - 3;	2
*	Multiplication	let x = 5 * 3;	15
/	Division	let x = 6 / 3;	2
%	Modulus (remainder)	let x = 7 % 3;	1
**	Exponentiation	let x = 2 ** 3;	8

2. Comparison Operators

These operators are used to compare two values and return a Boolean value (true or false).

Operator	Description	Example	Output
==	Equal to	5 == '5'	true
===	Strict equal to (value and type)	5 === '5'	false
!=	Not equal	5 != '6'	true
!==	Strict not equal	5 !== '5'	true
>	Greater than	6 > 3	true
<	Less than	2 < 5	true
>=	Greater than or equal to	5 >= 5	true
<=	Less than or equal to	4 <= 3	false

3. Logical Operators

Used to combine multiple conditions or expressions and return Boolean results.

Operator	Description	Example	Output
&&	Logical AND	(5 > 2) && (4 < 10)	true
\|\|	Logical OR	(5 < 2) \|\| (4 < 10)	true
!	Logical NOT	!(5 === 5)	false

4. Assignment Operators

Used to assign values to variables and combine with arithmetic operations.

Operator	Description	Example	Output
=	Assign	x = 10	10
+=	Add and assign	x += 5	15
-=	Subtract and assign	x -= 2	13
*=	Multiply and assign	x *= 2	26
/=	Divide and assign	x /= 2	13
%=	Modulus and assign	x %= 4	1

5. Bitwise Operators

Know more in Detail

Perform bit-level operations on binary representations of integers.

Operator	Description	Example	Output
&	Bitwise AND	5 & 3	1
\|	Bitwise OR	5 \| 3	7
^	Bitwise XOR	5 ^ 3	6
~	Bitwise NOT	~5	-6
<<	Left Shift	5 << 1	10
>>	Right Shift	5 >> 1	2
