JavaScript Basics 🚀

JavaScript is a powerful programming language that brings interactivity to websites. Here's a quick guide to its core concepts:

📌 Core Concepts

• Variables: Use let or const to declare variables. Example:

  let message = "Hello, World!";
  

  

• Data Types: Includes numbers, strings, booleans, arrays, and objects.

  

• Operators: Arithmetic (+, -, *, /), comparison (==, >, <), and logical (&&, ||) operators.

  

• Control Structures:

  • if/else for conditional logic
  • for/while loops for repetition
  • switch for multiple conditions
  

• Functions: Reusable blocks of code. Example:

  function greet(name) {
    return `Welcome, ${name}!`;
  }
