THE ORIGIN STORY
The 10-Day Miracle (1995)
In May 1995, a programmer named Brendan Eich was working at Netscape. He was asked to create a scripting language for the web browser. Incredibly, he wrote the first version of JavaScript in just 10 days.
Mocha
The original code name.
LiveScript
Shipped in Netscape 2.0 beta.
JavaScript

MYTH BUSTERS
The Biggest Myth
"JavaScript is just a simplified version of Java."
NO! They are completely different languages.
"Java is to JavaScript as Car is to Carpet."
The Reality
"JavaScript can only run in a browser."
NOT ANYMORE!
With Node.js, JavaScript runs on servers, robots, and even spaceships!
HOW DOES IT WORK?
The Engine (V8)
Computers don't understand JavaScript directly. They only understand 1s and 0s.
Your browser (like Chrome) has a JavaScript Engine (called V8). It acts like a translator, turning your code into machine commands instantly.
HALL OF FAME
Who uses JavaScript? Basically everyone.
