Free Preview — Chapter 1

JavaScript was created in 1995 by Brendan Eich and has grown to become the most widely used programming language in the world. Unlike many languages that run on servers or desktops, JavaScript was designed to run directly in web browsers — making it uniquely suited to building the interactive experiences we expect on the modern web.

// Your first JavaScript program
console.log("Hello, World!");

Every statement in JavaScript ends with a semicolon (though it is optional — JavaScript has Automatic Semicolon Insertion). We’ll explore code style best practices throughout the book.
