Module 4: React JS - Building Interactive UIs

Introduction to React

Explore the fundamentals of React, a popular JavaScript library for building user interfaces. Understand its core principles, such as components, JSX (JavaScript XML), and the virtual DOM. Learn about the creation and motivation behind React and its advantages in modern web development.

Setting Up the Development Environment

Learn how to set up a local development environment for React applications. This includes installing Node.js, using Create React App, and understanding the basic file structure of a React project.

React Components

Dive into the concept of components, the building blocks of any React application. Learn about functional and class components, props, and state. Understand how to create reusable components that manage their own state.

State and Lifecycle

Explore how React handles component state and lifecycle methods. Understand how to initialize state in constructor, use lifecycle methods for operations like mounting and updating components, and how state updates trigger UI re-renders.

Handling Events

Learn about handling events in React. This includes understanding synthetic events and how to bind event handlers in JSX. Practice creating interactive elements that respond to user inputs.

Conditional Rendering

Understand how to use JavaScript operators to conditionally render components based on different states or props. Learn techniques to handle dynamic content display and operational flows within React applications.

Forms and Controlled Components

Explore the handling of form inputs with controlled components. Understand the importance of controlled components for creating forms that directly manage form data via React state.

Lifting State Up

Understand the common pattern of lifting state up to shared ancestors to keep component state synchronized across the application. Learn how to pass data between sibling components through their parent.

Composition vs Inheritance

Explore how React recommends using composition over inheritance to solve problems. Understand how to use props and composition to reuse code among components.

Routing with React Router

Learn about using React Router to handle navigation in a single-page application. Understand how to configure and use dynamic routing to improve user experience.

Hooks in React

Get introduced to React Hooks, a feature that allows you to use state and other React features without writing a class. Understand commonly used hooks like useState, useEffect, and custom hooks.


Delve into more complex React topics such as context for global state, higher-order components, and using external state management libraries like Redux.
