ReactJS

Duration:  5 days – 35 hrs.

Overview

React JS is a powerful JavaScript library widely used for building user interfaces for web applications. It provides a component-based architecture, allowing developers to create reusable UI components and efficiently manage complex UIs. React JS has gained significant popularity due to its performance, flexibility, and large community support.

 

Objectives

• Understand the fundamentals of ReactJS: Gain a solid understanding of the key concepts and principles of ReactJS, including components, JSX syntax, virtual DOM, and state management.
• Learn component-based development: Understand the concept of component-based development and learn how to create reusable and modular components in ReactJS.
• Master JSX syntax: Familiarize yourself with JSX, a syntax extension for JavaScript that allows you to write HTML-like code in your React components, making it easier to create dynamic user interfaces.
• Handle component state and props: Learn how to manage component state and utilize props to pass data between components, enabling dynamic and interactive UIs.
• Work with React Router: Understand how to implement client-side routing in ReactJS using React Router, allowing for the creation of multi-page applications with navigation and URL management.

• Implement forms and user input handling: Gain knowledge on handling form inputs, implementing form validation, and managing user interactions in ReactJS applications.
• Integrate with APIs and fetch data: Learn how to make HTTP requests to APIs, fetch and display data in ReactJS applications, and handle asynchronous operations.
• Apply styling and CSS frameworks: Explore different approaches to styling React components, including using CSS, CSS-in-JS solutions, and popular CSS frameworks like Bootstrap or Material-UI.
• Test ReactJS components: Understand the basics of testing React components using testing frameworks and libraries to ensure the quality and reliability of your code.
• Optimize performance and best practices: Learn best practices for writing efficient and optimized ReactJS code, improving performance, and avoiding common pitfalls.
• Build a complete ReactJS application: Apply the knowledge and skills gained throughout the training to develop a complete ReactJS application, incorporating various features and concepts covered in the course.
