JavaScript Operators
Duration : 00:01:00
Arithmetic Operators:
Arithmetic operators perform mathematical operations on numbers.Example:
let x = 10;
let y = 5;
let sum = x + y;
console.log("Sum:", sum); // Output: Sum: 15
Assignment Operators:
Assignment operators are used to assign values to variables.Example:
let a = 10;
let b = 5;
a += b;
console.log("a:", a); // Output: a: 15
Comparison Operators:
Comparison operators compare two values and return a Boolean result.Example:
let num1 = 10;
let num2 = 5;
let isEqual = num1 === num2;
console.log("isEqual:", isEqual); // Output: isEqual: false String Operators:
String operators concatenate (join) strings or extract substrings.Example:
let str1 = "Hello, ";
let str2 = "world!";
let greeting = str1 + str2;
console.log(greeting); // Output: Hello, world!
Logical Operators:
Logical operators perform logical operations on Boolean values.Example:
let isTrue = true;
let isFalse = false;
let result = isTrue && isFalse;
console.log("result:", result); // Output: result: false
Bitwise Operators:
Bitwise operators manipulate the individual bits of numbers.Example:
let num1 = 5; // Binary: 101
let num2 = 3; // Binary: 011
let result = num1 & num2; // Binary: 001 (Decimal: 1)
console.log("result:", result); // Output: result: 1
Ternary Operators:
Ternary operators provide a concise way to write conditional expressions.Example:
let age = 20;
let status = age >= 18 ? "Adult" : "Minor";
console.log("status:", status); // Output: status: Adult
Type Operators:
Type operators determine the type of a value or check instance relationships.Example:
let value = "Hello";
let type = typeof value;
console.log("type:", type); // Output: type: string
