React & Modern Frontend
Build modern frontend interfaces with JavaScript foundations, components, routing, data flow, performance, testing, accessibility, and portfolio proof.
Start with the path, then open the rooms.
Work through the lessons in order. Each lesson starts with the concept, explains the vocabulary, then moves into examples, review checks, browser practice, and saved proof when it is useful.
Outcomes
React frontend engineering evidence
This course is organized around a role path, industry alignment, and proof a learner can keep.
- Map JavaScript data flow to component behavior.
- Design components, routes, forms, state, and performance decisions from user-visible states.
- Tie testing and accessibility evidence to behavior before portfolio polish.
- Component, route/form, state/performance, quality, and capstone proof cards.
- Data-flow notes and user-visible state maps.
- Learner explanations that connect React choices to testable user behavior.
React rooms should prove data flow, user states, and quality evidence before focusing on framework syntax.
Proof Loop
Examples support the reading, but they are not completion evidence by themselves.
Check Work must pass inside the sandbox before protected rooms can complete.
Learners keep proof by writing expected result, actual result, and next improvement in their own words.
Lessons, checks, explanations, and completion
This map shows what the learner needs to do in each room: learn the concept, pass Check Work when required, explain the result, and keep completion proof.
