ReactJS code consists of multiple components.EachReactJScomponent has its own controls and logic that are specific to the component. Components can be reused or even repurposed in other parts of the code to meet
ReactJS is a JavaScript library for building user interfaces with features such as JSX, and virtual DOM for efficient updates and unidirectional data flow.

Higher-Order Components (HOCs) are a powerful pattern in React.js that allows you to reuse component logic. HOCs are functions that take a component as an argument and return a new component with enhanced functionality. They are used for cross-cutting concerns such as code reuse, logic abstr...
These components are simple classes(made up of multiple functions that add functionality to the application). All class-based components are child classes for the component class of Reatjs. importReactfrom'react';importReactDOMfrom'react-dom/client';classCarextendsReact.Component{constructor(props){su...
Independent.A component might be a dependency, but it rarely has any dependencies of its own. Thiseases updates and software maintenance, while also reducing the need for time-consuming regression testing when components are changed. Interoperable.Interoperability enables components to work across diverse...
Things to do and look up: - `npx create-react-app --typescript` which installs a lot of stuff - Components - JSX - The difference between Props and State - Function Components and the useState hook And some time later: - hooks in general, like useEffect and custom hooks - refs and ...
What is a key in React? It’s pretty often that whenever we are to render multiple components based on a mapping operation, we also want to maintain the orders of the components according to the data they’ve been mapped from. From a developer’s perspective, it does seem straightforward....
React was created because the facebook development team wanted a better way to structure JavaScript applications. So, why use React.Js? Reusable components: Components are a huge part of what makes react so understanding them is crucial when programming with react components let you split your cod...
