React for Beginners is a nine-lab introduction to building browser interfaces with functional React components. Starting from a Vite project, you will edit JSX, compose components, pass data, manage local state, and add common interactions such as buttons, dynamic lists, conditional content, and forms.
Every lab is guided and focused on one concept. You run the development server, see changes in the built-in browser preview, and complete small code changes that build a practical mental model of React’s component-driven workflow.
What You Will Learn
- Explore a Vite React project, install dependencies, and run its development server
- Create, export, import, and compose functional components
- Write JSX with expressions, attributes, self-closing elements, and fragments
- Pass values from parent to child components with props, destructuring, and defaults
- Manage local component state and updates with the
useStateHook - Attach event handlers, inspect event objects, and prevent default browser actions
- Render content conditionally with ternaries, logical operators, variables, and state
- Map arrays to keyed elements and build controlled form inputs and submission handlers
Who This Course Is For
This course is for learners new to React who already understand basic JavaScript and want a guided introduction to modern functional components. It is also useful for frontend beginners who want to see how JSX, props, state, and browser events work together before building a larger application.
Prerequisites: Basic JavaScript is recommended, including functions, variables, arrays, objects, imports, and array map. Familiarity with HTML elements and attributes is helpful. No prior React or Vite experience is required.
Learning environment: All nine labs run in an Ubuntu 22.04 React WebIDE with Node.js, npm, an editor, terminal, and Web 8080 browser preview. Each lab uses a Vite React project; you start the development server and observe updates through hot module replacement.
Frequently Asked Questions
Will I build one complete React application?
No. You will build focused examples such as components, a counter, conditional views, lists, and a controlled form. The course establishes core React mechanics but does not include a cumulative capstone application.
Does the course use function components or class components?
It uses function components and the useState Hook. Class components and their lifecycle methods are not part of the curriculum.
Does it cover routing, APIs, or advanced Hooks?
No. React Router, data fetching, useEffect, Context, custom Hooks, TypeScript, testing, state-management libraries, and deployment are outside this beginner scope.
Do I need to install React on my own computer?
No. Each lab prepares a Vite React project in the provided WebIDE. You work with npm and the development server inside the lab environment, so a local React setup is not required for the exercises.
