Props is short for properties. When we need to deliver a value to a component, we use props. When using ‘Hello’ component in App component, it delivers the value of name. 2. Props delivered to components can be inquired through parameters. Props is delivered in the form of an object, and if you want to look up the ‘name’ value, you can look up ‘props.name’. Multiple props, unstructured assignmen..

Pros Single-Page Applications (SPAs) offer several advantages that make them a popular choice for modern web development. Here are some pros of SPAs: Enhanced User Experience: SPAs provide a smooth and responsive user experience by dynamically updating the content on the page without requiring a full page reload. Users can navigate through the application seamlessly, as the UI remains interactiv..

SPA stands for Single-Page Application, and it is a web application architecture that aims to provide a seamless user experience by loading and rendering all necessary resources on a single web page, instead of navigating to multiple pages. React is well-suited for building SPAs due to its component-based architecture and efficient rendering capabilities. In a React SPA, the initial HTML page is..

In React, the term "lifecycle" refers to the series of methods that are invoked at different stages of a component's existence, from initialization to destruction. These lifecycle methods allow you to perform specific tasks or implement logic at certain points in a component's lifecycle. React's lifecycle can be divided into three main phases: Mounting: This phase occurs when a component is bein..

React.Component / Component In React, a class is a way to define a component using ES6 class syntax. It allows you to create reusable components with encapsulated state and behavior. React class components are based on the JavaScript class keyword and are an alternative to functional components. To define a class component in React, you typically extend the base Component or **React.Component** ..

In React, both state and props are used to manage and pass data in components, but they serve different purposes. State: State is an internal data storage specific to a component. It represents the mutable data that can be changed over time. State is managed and controlled by the component itself. When state changes, the component re-renders to reflect the updated state. State is typically initi..

Babel is a tool that extands the grammar of JavaScript. It converts the latest, convenient, or experimental JavaScript grammar that is not yet supported into a formal JavaScript format, allowing it to run properly even in an older browser-like environment. For JSX to properly convert to JavaScript, there are several rules you must follow. At least two tags must be wrapped in one tag or use 'Frag..

JSX (JavaScript XML) is an extension to the JavaScript language syntax used in React. It allows you to write HTML-like code within JavaScript, making it easier to define the structure and appearance of UI components in React. With JSX, you can write HTML-like tags and include JavaScript expressions within curly braces {}. It provides a concise and intuitive way to define the UI hierarchy and the..

JavaScript Code: // JavaScript code for rendering a list of names const names = ['Alice', 'Bob', 'Charlie']; const listContainer = document.getElementById('list-container'); const list = document.createElement('ul'); names.forEach(name => { const listItem = document.createElement('li'); listItem.innerText = name; list.appendChild(listItem); }); listContainer.appendChild(list); React Code: // Rea..

Declarative syntax is a fundamental concept in React that defines how UI components are structured and rendered. In React, you describe the desired state of your user interface, and React takes care of updating the actual DOM to match that state. This declarative approach contrasts with an imperative approach, where you manually manipulate the DOM to reflect changes in the UI. In React's declara..
