🚀 JavaScript Operators and Expressions: A Complete Guide 🎯

🌟 What are Operators in JavaScript?

Operators in JavaScript are symbols that perform operations on values and variables. They help in performing mathematical, logical, comparison, and other operations.

🔹 Types of Operators in JavaScript

JavaScript has several types of operators:

1️⃣ Arithmetic Operators 2️⃣ Assignment Operators 3️⃣ Comparison Operators 4️⃣ Logical Operators 5️⃣ Bitwise Operators 6️⃣ String Operators 7️⃣ Ternary Operators

🔥 1️⃣ Arithmetic Operators (Used for mathematical calculations)

let a = 10;

let b = 5;

console.log(a + b); // Addition -> 15

console.log(a - b); // Subtraction -> 5

console.log(a b); // Multiplication -> 50

console.log(a / b); // Division -> 2

console.log(a % b); // Modulus -> 0

console.log(a **\ b); // Exponentiation -> 100000

🎯 2️⃣ Assignment Operators (Assign values to variables)

let x = 10;

x += 5; // x = x + 5 -> 15

x -= 2; // x = x - 2 -> 13

x *\= 3; // x = x 3 -> 39

x /= 3; // x = x / 3 -> 13

✅ 3️⃣ Comparison Operators (Compare values and return true/false)

console.log(10 == "10"); // true (loose equality, converts types)

console.log(10 === "10"); // false (strict equality, checks type too)

console.log(10 != 5); // true

console.log(10 > 5); // true

console.log(10 < 5); // false

🔥 4️⃣ Logical Operators (Used for combining conditions)

let isJSFun = true;

let isEasy = false;

console.log(isJSFun && isEasy); // false (AND operator)

console.log(isJSFun || isEasy); // true (OR operator)

console.log(!isJSFun); // false (NOT operator)

🎯 5️⃣ Bitwise Operators (Operate at the binary level)

console.log(5 & 1); // AND -> 1

console.log(5 | 1); // OR -> 5

console.log(5 ^ 1); // XOR -> 4

console.log(~5); // NOT -> -6

🔥 6️⃣ String Operators (Used to concatenate strings)

let firstName = "Vivek";

let lastName = "Varshney";

console.log(firstName + " " + lastName); // "Vivek Varshney"

🎯 7️⃣ Ternary Operator (Shorter if-else statement)

let age = 20;

let status = age >= 18 ? "Adult" : "Minor";

console.log(status); // "Adult"

🚀 Conclusion

Operators and expressions are the backbone of JavaScript logic. Understanding them helps in writing efficient and powerful code! 🔥
