Let’s go through Operators in JavaScript step by step.

🔹 Operators in JavaScript

👉 Operators are symbols that tell JavaScript to perform some operation on values (operands).

Example:

let x = 5 + 3; // + is an operator, 5 & 3 are operands

---

1️⃣ Arithmetic Operators

Used for mathematical operations.

Operator	Description	Example	Result
+	Addition	5 + 2	7
-	Subtraction	5 - 2	3
*	Multiplication	5 * 2	10
/	Division	5 / 2	2.5
%	Modulus (remainder)	5 % 2	1
**	Exponentiation	2 ** 3	8
++	Increment	x++	x = x + 1
--	Decrement	x--	x = x - 1

---

2️⃣ Assignment Operators

Used to assign values.

Operator	Example	Equivalent To
=	x = 5	x = 5
+=	x += 3	x = x + 3
-=	x -= 3	x = x - 3
*=	x *= 3	x = x * 3
/=	x /= 3	x = x / 3
%=	x %= 3	x = x % 3
**=	x **= 2	x = x ** 2

---

3️⃣ Comparison Operators

Used to compare values (returns true or false).

Operator	Description	Example	Result
==	Equal to (value only)	5 == "5"	true
===	Strict equal (value + type)	5 === "5"	false
!=	Not equal (value only)	5 != "5"	false
!==	Strict not equal (value + type)	5 !== "5"	true
>	Greater than	7 > 5	true
<	Less than	7 < 5	false
>=	Greater or equal	5 >= 5	true
<=	Less or equal	3 <= 5	true

---

4️⃣ Logical Operators

Used with boolean (true / false).

Operator	Description	Example	Result
&&	Logical AND	true && false	false
||	Logical OR	`true
!	Logical NOT	!true	false

---

5️⃣ Bitwise Operators (works on 32-bit numbers)

Operator	Description	Example	Result
&	AND	5 & 1	1
|	OR	5 | 1	5
^	XOR	5 ^ 1	4
~	NOT	~5	-6
<<	Left shift	5 << 1	10
>>	Right shift	5 >> 1	2

---

6️⃣ Ternary Operator (Conditional)

Shorthand for if...else.

let age = 18;
let result = (age >= 18) ? "Adult" : "Minor";
console.log(result); // "Adult"

---

7️⃣ Type Operators

Operator	Description	Example	Result
typeof	Returns type of variable	typeof 123	"number"
instanceof	Checks if object is an instance of a class	arr instanceof Array	true

---

✅ Summary

• Arithmetic → + - * / % ** ++ --
• Assignment → = += -= *= /= %= **=
• Comparison → == === != !== > < >= <=
• Logical → && || !
• Bitwise → & | ^ ~ << >>
• Ternary → condition ? trueValue : falseValue
• Type → typeof, instanceof
