Javascript Operators

JavaScript Operators

Operators in JavaScript are used to perform operations on variables and values. They can be classified into different types based on their functionality.

1️⃣ Arithmetic Operators (Perform mathematical operations)

Operator	Description	Example	Result
`+`	Addition	`5 + 2`	`7`
`-`	Subtraction	`5 - 2`	`3`
`*`	Multiplication	`5 * 2`	`10`
`/`	Division	`10 / 2`	`5`
`%`	Modulus (Remainder)	`10 % 3`	`1`
`**`	Exponentiation	`2 ** 3`	`8`

Example:

let a = 10;
let b = 5;
console.log(a + b); // Output: 15

2️⃣ Assignment Operators (Assign values to variables)

Operator	Description	Example
`=`	Assign value	`x = 10`
`+=`	Add and assign	`x += 5` (same as `x = x + 5`)
`-=`	Subtract and assign	`x -= 5`
`*=`	Multiply and assign	`x *= 5`
`/=`	Divide and assign	`x /= 5`

Example

let x = 10;
x += 5;  // x = x + 5;
console.log(x); // Output: 15

3️⃣ Comparison Operators (Compare values, return `true` or `false`)

Operator	Description	Example	Result
`==`	Equal to (checks value)	`5 == "5"`	`true`
`===`	Strict equal (checks type & value)	`5 === "5"`	`false`
`!=`	Not equal	`5 != 3`	`true`
`!==`	Strict not equal	`5 !== "5"`	`true`
`>`	Greater than	`10 > 5`	`true`
`<`	Less than	`10 < 5`	`false`
`>=`	Greater than or equal	`10 >= 10`	`true`
`<=`	Less than or equal	`5 <= 3`	`false`

Example

console.log(10 > 5); // Output: true
console.log(5 === "5"); // Output: false

4️⃣ Logical Operators (Used in conditions)

Operator	Description	Example	Result
`&&`	AND (Both true)	`true && false`	`false`
`		`	OR (At least one true)
`!`	NOT (Reverse)	`!true`	`false`

Example

let isAdult = true;
let hasID = false;
console.log(isAdult && hasID); // Output: false

5️⃣ Bitwise Operators (Operate on binary numbers)

Operator	Description	Example
`&`	AND	`5 & 1`
`	`	OR
`^`	XOR	`5 ^ 1`
`~`	NOT	`~5`
`<<`	Left Shift	`5 << 1`
`>>`	Right Shift	`5 >> 1`

Example

console.log(5 & 1); // Output: 1 (Binary: 101 & 001 = 001)

6️⃣ String Operators (Used for text manipulation)

Operator	Description	Example
`+`	Concatenation	`"Hello " + "World"`
`+=`	Append and assign	`text += "JS"`

Example

let str = "Hello ";
str += "World!";
console.log(str); // Output: Hello World!

7️⃣ Ternary Operator (`? :`) (Shortens `if-else`)

Syntax:

Example

let age = 20;
let message = (age >= 18) ? "Adult" : "Minor";
console.log(message); // Output: Adult

Conclusion

JavaScript has various operators for performing different operations like arithmetic, comparison, logical, bitwise, and more.
Arithmetic operators perform calculations.
Comparison operators compare values.
Logical operators are useful in conditions.
Ternary operator simplifies if-else conditions.
