OPERATORS IN JAVASCRIPT

OPERATORS IN JAVASCRIPT:

Operators in JavaScript are special symbols or keywords used to perform operations on values and variables. They are used for calculations, assigning values, comparing values, and making logical decisions.

For example:

`let a = 10;
let b = 5;

let result = a + b;
console.log(result); // 15`

Types of Operators in JavaScript

JavaScript mainly provides the following types of operators:

1.Arithmetic Operators
2.Assignment Operators
3.Comparison Operators
4.Logical Operators
5.Increment and Decrement Operators
6.Ternary Operator
7.String Operators
8.Bitwise Operators
9.Type Operators

1. Arithmetic Operators

Used to perform mathematical calculations.
Operators: +, -, , /, %, *

Example:

`let a = 10;
let b = 5;

console.log(a + b); // 15`

2. Assignment Operators

Used to assign values to variables.
Operators: =, +=, -=, *=, /=, %=

Example:

`let a = 10;
a += 5;

console.log(a); // 15`

3.Comparison Operators

Comparison operators compare two values and return a Boolean

Example:

console.log(10 > 5); // true
console.log(10 < 5); // false
console.log(10 >= 10); // true
console.log(5 <= 10); // true

4. Logical Operators

Used to combine multiple conditions.

Example:

AND &&

Both conditions must be true.

let age = 20;
let hasID = true;

console.log(age >= 18 && hasID);

Result:

true

Example:

let age = 20;

if (age >= 18 && age <= 60) {
console.log("Allowed");
}

OR ||

At least one condition must be true.

let isStudent = false;
let isEmployee = true;

console.log(isStudent || isEmployee); // true

NOT !

Reverses a Boolean value.

let loggedIn = true;

console.log(!loggedIn); // false

5.String Operators

The + operator can be used to join strings.

This is called concatenation.

Example:

`let firstName = "John";
let lastName = "Doe";

let fullName = firstName + " " + lastName;

console.log(fullName);
`
