01Understand React, the browser, and the app we will buildExplain how components turn data into interface elements and identify what runs in the browser.Free preview02Set up Node, Vite, and your first React pageInstall the pinned starter in an independent folder, run its tests, and identify the React entry point.Free preview03Write JSX that renders safe, semantic HTMLUse JSX expressions, className, and semantic elements while keeping user text escaped.Course04Pass data through reusable componentsExtract a component with explicit props and keep rendering free of data mutation.Course05Render application lists with stable keysMap records to rows using stable identifiers that survive filtering, editing, and reordering.Course06Use state and events without mutating recordsRespond to clicks with state updates and explain when to use a functional state setter.Course07Build controlled, labeled application formsConnect input values to a draft object and submit explicitly without reloading the page.Course08Validate and create a complete applicationValidate strings, dates, statuses, and URLs before committing a normalized new record.Course09Edit and remove records by stable identityImplement immutable updates and confirmed deletion without changing unrelated records.Course10Search and filter without duplicating stateDerive matching records from the source list and combine search and status conditions.Course11Paginate the filtered list and preserve contextClamp page values, slice after filtering, and keep return navigation tied to the active search.Course12Persist browser data with a versioned schemaValidate localStorage data, preserve an empty store, and avoid overwriting damaged or newer data.Course13Use Effects only for external synchronizationDistinguish event logic and derived rendering from storage synchronization and cleanup.Course14Route between pages and protect unsaved editsUse React Router links and parameters with hash-based routes, validated return paths, and a dirty-form blocker.Course15Fetch templates with loading, error, and cancellation statesFetch and validate local JSON while handling HTTP failures, retry, empty responses, and abandoned requests.Course16Test rules and user interactionsRun deterministic domain tests and component tests that protect observable learner workflows.Course17Add a TypeScript boundary without confusing types with validationType component props and status values while continuing to validate unknown runtime data.Course18Debug stale state and review generated codeIsolate state, mutation, and Effect mistakes using a reproduction and a regression test.Course19Build and deploy a static React applicationBuild static assets, verify a production preview, and explain hosting paths, hash routes, and public client variables.Course20Finish the tracker and prove its acceptance criteriaCheck the complete app against a repeatable acceptance checklist and choose a scoped independent improvement.Course
