JavaScript Introduction

1What is JavaScript?✨

JavaScript is a versatile programming language that makes web pages interactive and dynamic. It's one of the core technologies of the web, alongside HTML and CSS!

2Why Learn JavaScript?🎯

• ✓ Essential for web development
• ✓ Enables interactive features on websites
• ✓ Used by major companies like Facebook, Google, and Microsoft
• ✓ Great for building games and apps

3Your First Program💡

Every programmer writes this first:
console.log("Hello, World!");

This tells JavaScript to display text in the console.

4JavaScript Basics🚀

• Commands tell JavaScript what to do
• console.log() shows output in the console
• JavaScript uses variables to store data
• It's case-sensitive, so "myVariable" and "myvariable" are different

5Variables and Data Types🔍

JavaScript has several data types, including:
- Numbers (e.g., 10, 3.14)
- Strings (e.g., "Hello")
- Booleans (true or false)

6You can declare a variable like this:⭐

let myNumber = 42;
