React: Build Modern, Scalable, and Interactive Web Applications

Uplatz offers this comprehensive course on React: Build Modern, Scalable, and Interactive Web Applications. It is a self-paced course with video lectures. You will be awarded Course Completion Certificate at the end of the course.

React is a JavaScript library developed by Meta for building fast, scalable, and interactive user interfaces. It is primarily used for single-page applications (SPAs), where content updates dynamically without requiring a full page reload.

React follows a component-based architecture, allowing developers to build reusable UI components that efficiently update and render based on changing data.

In summary, React is a powerful, fast, and scalable library that simplifies frontend development. Whether you're building small applications or large-scale web platforms, React provides the tools, performance, and flexibility needed for modern web development.

React works by efficiently updating and rendering components using a concept called the Virtual DOM (Document Object Model).

1. Virtual DOM – React creates a lightweight copy of the real DOM.
2. State & Props – Components manage their own data (state) and receive external data (props) from other components.
3. Reconciliation – When data changes, React updates only the necessary parts of the DOM instead of re-rendering the entire page.
4. Component-Based Structure – The UI is divided into reusable components, making code easier to manage and scale.
5. One-Way Data Binding – Data flows in a single direction, ensuring predictable state management.

• UI is broken into reusable components, improving modularity and maintainability.

• React updates the Virtual DOM first and then syncs changes efficiently to the real DOM, improving performance.

• A syntax extension that allows developers to write HTML-like code inside JavaScript, making UI code more readable.

• Functions like useState, useEffect, and useContext allow developers to manage state and side effects without using class components.

• State stores data within a component.
• Props pass data from one component to another.

• Enables navigation between different pages/views in a React application without a full page reload.

• Ensures predictable and controlled data updates, preventing unexpected UI changes.

• With frameworks like Next.js, React supports faster initial page loads and improved SEO.

• Built-in Context API and external libraries like Redux, MobX, and Zustand help manage global application state.

• Works with tools like Webpack, Babel, GraphQL, Firebase, and REST APIs.

• Virtual DOM reduces unnecessary re-renders, making applications faster.

• Code is modular, reducing duplication and improving maintainability.

• Simple syntax (JSX) and a strong developer community make React easy to adopt.

• Large ecosystem with open-source libraries, plugins, and frameworks like Next.js and React Native.

• With React Native, developers can build mobile apps using the same React knowledge.

• Improved search engine indexing using Next.js for server-side rendering.

• Suitable for small projects to large enterprise applications.

• React's Context API and third-party tools like Redux make managing global state easier.

• Official React DevTools for debugging and performance optimization.

• Used by top companies like Facebook, Instagram, Netflix, Airbnb, and Uber.
