React & Modern Frontend

Build modern frontend interfaces with JavaScript foundations, components, routing, data flow, performance, testing, accessibility, and portfolio proof.

Course Overview

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.

Competency Focus
  • 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.
Work You Can Show
  • 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.
Completion Gate

React rooms should prove data flow, user states, and quality evidence before focusing on framework syntax.

Proof Loop

6 examples to inspect

Examples support the reading, but they are not completion evidence by themselves.

0/6 graded rooms passed

Check Work must pass inside the sandbox before protected rooms can complete.

0 explanations saved

Learners keep proof by writing expected result, actual result, and next improvement in their own words.
