Operator

Operators in JavaScript

Arithmetic Operators

Perform basic math operations:

Operator	Example	Result
+	2 + 3	5
-	5 - 2	3
*	4 * 2	8
/	10 / 2	5
%	7 % 3	1
**	2 ** 3	8

Example

let a = 2 + 1   // 3
let b = a - 1   // 2
let c = b * 3   // 6
let d = c / 2   // 3
let e = 8 % 3   // 2
let f = 2 ** 3  // 8

Assignment Operators

Assign or update values:

Operator	Example	Meaning
=	x = 5	Assign 5 to x
+=	x += 3	x = x + 3
-=	x -= 2	x = x - 2
*=	x *= 4	x = x * 4
/=	x /= 2	x = x / 2

Example:

let x = 5  // 5
x += 3     // 8
x -= 2     // 6
x *= 4     // 24
x /= 2     // 12

Comparison Operators

Return true or false by comparing values:

Operator	Example	Result
==	5 == '5'	true (loose equality)
===	5 === '5'	false (strict equality)
!=	5 != 10	true
!==	5 !== '5'	true
<	3 < 5	true
>	7 > 2	true
<=	4 <= 4	true
>=	6 >= 8	false

Logical Operators

Work with boolean values:

Operator	Example	Meaning
&&	true && false	AND (both true)
`		`
!	!true	NOT (negation)
