Speak the language of the web — in about eight hours.HTML gives a page its bones and CSS its looks, but JavaScript makes it do things. This book teaches you modern JavaScript from your very first console.log to a complete, working web app — in short, plain-English chapters you can finish in about eight hours.Every example builds one project: the website of the Daily Grind, a small coffee shop. Chapter by chapter you'll render its menu from data, filter it with buttons, take orders with a form that politely refuses bad input, remember the cart between visits, and load fresh data from a server — the exact skills behind every interactive site you use daily.You'll learn to:Write modern JavaScript (ES6+): let/const, arrow functions, template literals, destructuring, and classesWork with strings, arrays, and objects — and the array superpowers map, filter, and reduceControl the page with the DOM: select, change, create, and remove elementsHandle clicks, keystrokes, and form submissions with eventsSave data with localStorage and JSON so your site remembers its usersMaster async JavaScript: promises, async/await, and fetching live data from APIsDebug like a professional with DevTools, breakpoints, and error handlingTake a first confident step into Node.js and see where tooling fitsEvery screenshot in the book shows real, executed output — actual console sessions, actual timings, an actual working site. Each chapter ends with an “In Short” recap and “Try It Yourself” exercises (hints and full solutions included), three checkpoint self-tests tell you honestly whether to press on or circle back, and six appendices make it a reference you'll keep beside the keyboard long after hour eight.No JavaScript experience required. If you can edit a text file and open a browser, you can learn the language of the web — this weekend.©2026 John Rouda (P)2026 John Rouda Programmation et développement de logiciels
