Lecture 2: What is React.? In this lecture, we will explore the fundamentals of React.js and gain a clear understanding of what React is and why it has become one of the most popular JavaScript libraries for building user interfaces. During this lecture, we will cover the following topics: 1. Introduction to React: We will begin by introducing React.js and its core concepts. You will learn about React's philosophy of building UI components and how it focuses on a component-based architecture. 2. Virtual DOM: React utilizes a virtual DOM (Document Object Model) to efficiently update and render components. We will delve into the virtual DOM concept and understand how it improves performance by minimizing the number of actual DOM manipulations. 3. React Components: Components are the building blocks of React applications. We will explore what React components are and how they enable us to encapsulate and reuse UI elements. You will learn about functional components and class components, as well as their respective use cases. 4. JSX: JSX is a syntax extension used in React that allows us to write HTML-like code within JavaScript. We will discuss how JSX works, its benefits, and how it simplifies the process of composing components. 5. State and Props: React provides a mechanism to manage component data using state and props. We will explore the concepts of state and props and understand how they enable us to create dynamic and interactive UIs. 6. React Lifecycle: React components go through a series of lifecycle phases. We will cover the different lifecycle methods and their purposes, including mounting, updating, and unmounting phases. By the end of this lecture, you will have a solid grasp of the core concepts of React.js, including its component-based architecture, virtual DOM, JSX, state and props, and the component lifecycle. This knowledge will serve as a strong foundation for working with React and building robust and scalable user interfaces. Let's dive into the world of React and unlock its potential!
