📌 What are JavaScript Operators?
Operators in JavaScript are used to perform operations on values and variables. 💡
They are essential building blocks for expressions, conditions, and logic in your code.
📋 Types of Operators
- 🔹 Arithmetic Operators
- 🔸 Assignment Operators
- 🔹 Comparison Operators
- 🔸 Logical Operators
- 🔹 Unary Operators
- 🔸 Ternary Operator
- 🔹 Bitwise Operators
🔹 Arithmetic Operators
| Attribute | Description |
|---|---|
+ | Addition (e.g., a + b) |
- | Subtraction (e.g., a - b) |
* | Multiplication (e.g., a * b) |
/ | Division (e.g., a / b) |
% | Modulus (remainder) (e.g., a % b) |
++ | Increment (e.g., a++) |
-- | Decrement (e.g., a--) |
🔸 Assignment Operators
| Attribute | Description |
|---|---|
= | Assigns value (e.g., x = 10) |
+= | Adds and assigns (e.g., x += 5) |
-= | Subtracts and assigns (e.g., x -= 5) |
*= | Multiplies and assigns (e.g., x *= 5) |
/= | Divides and assigns (e.g., x /= 5) |
%= | Modulus and assigns (e.g., x %= 5) |
🔹 Comparison Operators
| Attribute | Description |
|---|---|
== | Equal to (abstract equality) |
=== | Strict equal to (value and type) |
!= | Not equal to |
!== | Strict not equal to |
> | Greater than |
< | Less than |
>= | Greater than or equal to |
<= | Less than or equal to |
🔸 Logical Operators
| Attribute | Description |
|---|---|
&& | Logical AND (true if both are true) |
|| | Logical OR (true if at least one is true) |
! | Logical NOT (inverts the result) |
🔹 Unary Operator
| Attribute | Description |
|---|---|
typeof | Returns the data type of a variable |
delete | Deletes a property from an object |
🔸 Ternary Operator
| Attribute | Description |
|---|---|
condition ? trueExpr : falseExpr | Shorthand for if-else statement |
🔹 Bitwise Operators
| Attribute | Description |
|---|---|
& | AND |
| | OR |
^ | XOR |
~ | NOT |
<< | Left shift |
>> | Right shift |
