Modern Front-End Architecture
Move beyond basic HTML and CSS to build scalable, high-performance web applications. Learn to architect components, manage complex state, and optimize the user experience like a professional engineer.
Like Duolingo, but for Modern Front-End Architecture. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through Architecting the Interface, Data and Interaction, and Performance and Polish. It assumes you already know the basics.

Key ideas in Modern Front-End Architecture
- Visual repetition indicates a single reusable component definition
- Props allow a component to stay generic by accepting external configuration
- The single responsibility principle dictates where one component ends and another begins
- Hardcoding values inside a component prevents it from being reused in different UI states
- A component tree maps how smaller UI pieces nest inside larger layout containers
- Passing a 'variant' prop lets the parent control the component's appearance
- The process of decomposing a visual mockup into a nested component tree
- Applying props to make a component adaptable to different contexts
- Composition uses the 'children' prop to wrap and augment existing components
- Inheritance creates rigid dependencies that are harder to maintain than nested components
- Nesting components allows for flexible layouts without modifying the internal logic of the child
- Presentational components are 'dumb' and shouldn't know where data comes from
- Container components act as the data-fetching layer for a specific feature
- Separating concerns makes UI components easier to test and style in isolation
- Distinguishing between presentational and container components
- Understanding composition as the primary method for building complex UIs

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Modern Front-End Architecture the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
