Modern Web Development: Foundations
Component-driven, typed front-end development as it is actually practiced on real teams today.
Course overview
This course builds the practical foundation for modern front-end work: component structure, typed data, and the habits that keep an interface maintainable as it grows. It is built around real interface problems, not isolated syntax drills.
What you’ll learn
- Structure a UI into components with clear responsibilities
- Use typed data to prevent an entire category of bugs
- Reason about state instead of guessing at it
