📄️ React Basics
React is a JavaScript library for building user interfaces. It was developed and is maintained by Facebook and is widely used in the development of web and mobile applications. React allows developers to build reusable UI components and manage the states of those components in a predictable way. It uses a virtual DOM, which makes updates to the user interface faster and more efficient. React also uses a component-based architecture, which allows for easy separation of concerns and makes code more modular and maintainable. React is a powerful tool for building dynamic and responsive user interfaces, and is a popular choice among developers today. This chapter will cover the basics of React, including setting up a development environment, creating and using components, managing state and props, and working with events and forms.
📄️ Introduction to Function-based React Components
React is a JavaScript library for building user interfaces. One of the core concepts in React is the component. A component is a piece of code that represents a part of a user interface. In this tutorial, we will focus on function-based components, which are components defined as JavaScript functions.
📄️ Component Props
In React, component props are used to pass data from a parent component to a child component. Props are similar to function arguments in that they are passed in as an object when the component is called.
📄️ Component State
In React, the component state is an object that holds information that can change and affect the behavior or rendering of a component. The state is managed by the component itself and can be updated using the setState() method.
📄️ Event Handler
Event handling in function based components in React involves using event handlers to handle specific events that occur within the component, such as a button click or a form submission.
📄️ Conditional Rendering for functional components
Conditional rendering in functional components is similar to how it is done in class-based components. You can use JavaScript's built-in control flow statements, such as if-else or ternary operators, to determine which elements to render.
📄️ Higher-Order Components (HOCs)
Higher-Order Components (HOCs) are a way to reuse component logic. They are a pattern in React that allow you to share common functionality between components without having to repeat the same code in multiple places.
📄️ React Hooks
React Hooks are a way to use state and other React features in function-based components. They were introduced in React 16.8 as an alternative to class-based components and have since become the recommended way to write components in React.
