Embark on a guided tour through the Grand ClojureScript Hotel, where each "floor" presents a curated suite of interactive projects that teach you both the art and science of ClojureScript. Your journey begins in the lobby. Here, you&ll learn foundational skills like setting up a live-reloading workflow, driving Canvas animations, and handling user input. From there, you&ll move up through floors devoted to generative art, reactive UIs, data visualization, multimedia processing, 3D graphics, machine learning, and mobile apps. On every floor, you&ll work through bite-sized, hands-on demos: from a classic Pong game and fractal renderers to real-time audio wave viewers, PixiJS arcade games, and a wellness-focused "better-sleep" mobile app. Along the way, you&ll integrate popular JavaScript libraries (like Reagent, Re-frame, Nivo, Recharts, Tone.js, and Three.js) using idiomatic ClojureScript. This hands-on approach ensures you gain practical expertise in state management, interop patterns, and modern rendering pipelines. By the end of your stay, you&ll have built a diverse portfolio of projects-each fully explained step by step and you&ll know exactly how to launch your own robust ClojureScript applications on the web and mobile. Whether you&re a seasoned Clojure developer branching into browser-based interactivity, or a front-end engineer eager to explore functional programming, this book delivers the recipes, patterns, and creative spark to craft truly delightful user experiences You Will Learn To: Master REPL-driven development, tooling, and elegant namespace organization in ClojureScript. Create dynamic graphics and generative art using Canvas, Quil and Motion.js. Build state-driven interfaces with Reagent and Re-frame, and seamlessly integrate third-party widget libraries.  Visualize data and multimedia with Nivo/ Recharts, Tone.js audio analyzers, and Canvas video filters. Develop 2D/3D games (PixiJS, Three.js), implement neural networks in the browser, and build mobile-native applications . This Book Is For: JavaScript Developers curious about functional programming and the ClojureScript ecosystem. Clojure Enthusiasts branching from the backend into dynamic, browser- and mobile-based inter activity. Front-End Engineers seeking a hands-on, project-centric path to mastering graphics, visualization, and games. Creative Coders looking for a robust language to build state-driven, delightful user experiences
