When a task is encapsulated into a software component, that component becomes an independent and well-understood element. Each time that component is used or reused, it performs the same task in the same way, ensuring that the component's appearance and output are consistent. As that component...
7) A ReactElement is a light, stateless, immutable, virtual representation of a DOM Element 8) You can also create a Element directly React.createElement(arg) where arg can be a html tag name, or a React Component class. Class-Based Components: 1) Class syntax is one of the most...
The state object is used to store the data that belongs to that particular component. Functional components are stateless. It can be done via Hooks if you want to use ‘state’ in functional components. No other class can access the data stored in the state as it is private. To access t...
ReactJs as a JavaScript library created by Facebook that lets us build dynamic user interfaces. What this dynamic user interface even means is that we have a web app with three timers on it, we have the ability to create and delete a timer when you click on a button to create a timer...
Let’s take an example: Look at the Facebook page, which is entirely built on React, to understand how react does works. As the figure shows, ReactJS divides the UI into multiple components, making the code easier to debug. This way, each function is assigned to a specific component, ...
TheReact docssay that higher-order componentstake a componentandreturn a component. The use of higher-order components comes in handy when you are architecturally ready for separating container components from presentation components. The presentation component is often a stateless functional component that...
1. Component-based architecture: React encourages the creation of reusable components, which makes it easier to maintain and scale applications. Components are self-contained, modular pieces of UI that can be combined to create complex interfaces. ...
MEAN is a collection of technologies (MongoDB, Express.js, Angular.js, and Node.js) associated with JavaScript, which is used to build web-based applications. MEAN stack is responsible for the development of each component of website development from client-side/server-side to database ...
One of the key features of React is its component-based architecture, which allows you to break down your user interface into reusable and independent building blocks called components.In this article, we will explore two types of components in React: functional components and class components....
We will learn how to install and configure React Router, along with adding a <Switch> component, exact prop, and parameters to routes. Chapter 12, Anti-Patterns to be Avoided, is all about the common anti-patterns we should avoid when using React. We will study why mutating the state is...
