A visual, interactive journey through the evolution of frontend development. See exactly how a Todo List application transforms as it is rebuilt across 5 different stages of web technology—from raw structure to modern typed components.
The raw skeleton of the web. Structure and content only, relying on the browser's default appearance.
Visual presentation. We take the exact same HTML and make it beautiful using a modern stylesheet.
Behavior and logic. We write scripts to manipulate the DOM, finally making the Todo list interactive.
Components and global state. The modern UI powerhouse that simplifies how we build complex interfaces.
Static typing and compile-time safety. We prevent bugs before they happen by defining exact shapes for our data.
Core fundamentals, quick tutorials, and interactive theory. From HTML to TypeScript with hands-on practice.
Step-by-step project tutorials. Build real apps with guidance, theory, and instant feedback.
Hands-on interactive challenges. Break code, see errors, learn from mistakes with immediate feedback.
