JavaScript Operators

Arithmetic Operators

Arithmetic operators are used to perform mathematical calculations.

let a = 10;
let b = 5;

let sum = a + b;       // Addition
let difference = a - b; // Subtraction
let product = a * b;   // Multiplication
let quotient = a / b;  // Division
let remainder = a % b; // Modulus

console.log("Sum: " + sum);            // Output: Sum: 15
console.log("Difference: " + difference); // Output: Difference: 5
console.log("Product: " + product);    // Output: Product: 50
console.log("Quotient: " + quotient);  // Output: Quotient: 2
console.log("Remainder: " + remainder); // Output: Remainder: 0

Assignment Operators

Assignment operators are used to assign values to variables.

let x = 10;  // Assignment
x += 5;      // Addition assignment
x -= 3;      // Subtraction assignment
x *= 2;      // Multiplication assignment
x /= 4;      // Division assignment
x %= 3;      // Modulus assignment

console.log("Value of x: " + x);  // Output: Value of x: 2

JavaScript

Comparison Operators

Comparison operators are used to compare two values and return a boolean result (true or false).

let a = 10;
let b = 5;

console.log(a == b);  // Equal to (Output: false)
console.log(a != b);  // Not equal to (Output: true)
console.log(a > b);   // Greater than (Output: true)
console.log(a < b);   // Less than (Output: false)
console.log(a >= b);  // Greater than or equal to (Output: true)
console.log(a <= b);  // Less than or equal to (Output: false)

JavaScript
 
let a = 10;let b = 5;​console.log(a == b);  // Equal to (Output: false)console.log(a != b);  // Not equal to (Output: true)console.log(a > b);   // Greater than (Output: true)console.log(a < b);   // Less than (Output: false)console.log(a >= b);  // Greater than or equal to (Output: true)console.log(a <= b);  // Less than or equal to (Output: false)

Logical Operators

Logical operators are used to combine multiple boolean expressions or values.

let a = true;
let b = false;

console.log(a && b);  // Logical AND (Output: false)
console.log(a || b);  // Logical OR (Output: true)
console.log(!a);      // Logical NOT (Output: false)

JavaScript
 
let a = true;let b = false;​console.log(a && b);  // Logical AND (Output: false)console.log(a || b);  // Logical OR (Output: true)console.log(!a);      // Logical NOT (Output: false)
