React Fundamentals
- What is React & JSX — React is a JavaScript library for building user interfaces using reusable components.
- Components & Props — Components are reusable building blocks of a React application.
- Building & Deploying a React App (Vite) — React apps are written in JSX and need to be compiled to regular JavaScript before browsers can run them.
State & Hooks
- useState & Rendering — State is data that changes over time in a React component.
- useEffect & Side Effects — The `useEffect` hook lets you perform side effects in functional components.
Interactivity
- Handling Events & Forms — React events work similarly to DOM events but with some differences.
Rendering Patterns
- Lists & Keys — Rendering lists in React is done using the `map()` function to transform an array of data into an array of JSX elements.
- Conditional Rendering — Conditional rendering in React means showing different UI based on a condition.
Advanced
- useContext & Lifting State — As React apps grow, passing props through many levels of components becomes tedious ("prop drilling").
- Fetching Data from an API — APIs (Application Programming Interfaces) let your React app fetch data from servers.
Who this React course is for
School and college students in India starting from zero, and anyone revising React for placements, board practicals or a project. There is no prerequisite beyond being able to type — the first lessons assume no programming background at all.
How to study this course
- Read the lesson, then run the example in the built-in editor before moving on — reading code is not the same as writing it.
- Try the practice task at the end of each lesson. Getting it wrong and fixing it is where the learning happens.
- When you are stuck, ask the free AI Tutor to explain that specific line rather than skipping ahead.
