Operators in JS

JavaScript operators are symbols used to perform operations on variables and values.

1. Arithmetic operators used for mathematical calculations.

let a = 10, b = 3;

console.log(a + b); // 13 (Addition)
console.log(a - b); // 7  (Subtraction)
console.log(a * b); // 30 (Multiplication)
console.log(a / b); // 3.33... (Division)
console.log(a % b); // 1  (Remainder)
console.log(a ** b); // 1000 (Power)

1. Assignment operators used to assign values to variables.

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

like =,+=,-=,*=,/=

1. Comparison operators used to compare two values. Results true or false

console.log(10 > 5);   // true
console.log(10 < 5);   // false
console.log(5 == "5"); // true
console.log(5 === "5"); // false
console.log(5 != 3);   // true

1. Logical operators used to combine or reverse conditions.

console.log(true && false); // false (AND)
console.log(true || false); // true  (OR)
console.log(!true);         // false (NOT)

1. Increment or Decrement operators used to increase or decrease a value by 1

let x = 5;
x++;
console.log(x); // 6

x--;
console.log(x); // 5

1. Ternary opertors short way to write an if...else condition.

let age = 20;
let result = age >= 18 ? "Adult" : "Minor";

console.log(result); // Adult
