Modular Design Systems
This started as an interactive lesson, but it works just as well as a post about why modularity matters in both software architecture and UX.
What it covers
- High cohesion and low coupling
- Why modularity shows up in physical systems like LEGO and automobiles
- How Atomic Design helps prevent logic leakage in UI code
- Module patterns in JavaScript, including a live event-bus simulator
The embedded lesson is still here if you want the hands-on version:
This material has been rebuilt as a native, accessible lesson within the Systems Engineering Foundations hub. The new version preserves the strongest cohesion, coupling, Atomic Design, JavaScript modules, and event-bus material while adding structured citations, glossary links, progress, responsive interactions, and assessment explanations.
