javascript operators

1.  Arithmetic Operators:
JavaScript supports standard arithmetic operators such as addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). These operators facilitate basic mathematical calculations within your code.

let a = 10;
let b = 3;
let sum = a + b; // 13
let difference = a - b; // 7
let product = a * b; // 30
let quotient = a / b; // 3.333...
let remainder = a % b; // 1

2. Assignment Operators:
Assignment operators are used to assign values to variables. The basic assignment operator is “=”, but JavaScript also offers shorthand versions like +=, -=, *=, and /=.

let x = 5;
x += 3; // equivalent to x = x + 3; // x is now 8

3. Comparison Operators:
These operators are crucial for making decisions in your code. They compare values and return a Boolean result.

let p = 5;
let q = '5';

console.log(p == q); // true (loose equality)
console.log(p === q); // false (strict equality)
console.log(p !== q); // true (strict inequality)

4. Logical Operators:
Logical operators are used to combine and manipulate Boolean values. The most common ones are AND (&&), OR (||), and NOT (!).

let sunny = true;
let warm = true;

if (sunny && warm) {
console.log('Perfect day!');
}

5. Unary Operators:
Unary operators work with a single operand. The most common unary operator is the negation operator (!).

let isRainy = false;
let isNotRainy = !isRainy; // true

6. Ternary Operator:
The ternary operator is a concise way to write an if-else statement in a single line.

let age = 20;
let status = (age >= 18) ? 'Adult' : 'Minor';

7. Bitwise Operators:
Bitwise operators manipulate the binary representation of numbers at the bit level. While they are not as commonly used, they can be powerful in specific scenarios.

let x = 5; // binary representation: 101
let y = 3; // binary representation: 011

let result = x & y; // bitwise AND: 001 (1 in decimal)
