Day 29: Variables, Data Types & Operators

⚡ Day 29: Variables, Data Types & Operators

🔹 Variables

Variables store data values. In JavaScript, you can declare them using var, let, or const.

let name = "Rahul";
const age = 22;
var city = "Hyderabad";
  • let: Block-scoped, can be reassigned
  • const: Block-scoped, cannot be reassigned
  • var: Function-scoped (old way, avoid if possible)

🔹 Data Types

  • String: "Hello"
  • Number: 42
  • Boolean: true or false
  • Object: {name: "Rahul", age: 22}
  • Array: [10, 20, 30]
  • Undefined, Null

🔹 Operators

Operators perform actions on values:

  • Arithmetic: +, -, *, /, %
  • Comparison: ==, ===, !=, !==, >, <, >=, <=
  • Logical: &&, ||, !
  • Assignment: =, +=, -=
