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..

Virtual DOM Problem with websites made with existing html / CSS / js Whenever a DOM change occurs due to some interaction, the render tree is recreated. That is, the style of all elements is recalculated. This provides the potential for the web to slow down when there is a lot of interaction. Virtual DOM is a copy of the real DOM into memory. In React, the Virtual DOM (Document Object Model) is ..

Component-Based Architecture In React, Component-Based Architecture is a fundamental concept that forms the basis of building user interfaces (UIs). React encourages developers to break down the UI into small, reusable components, which are self-contained units responsible for their own rendering and behavior. These components can be composed together to form complex UI structures. Here are the ..

Component-Based Architecture: React follows a component-based architecture, where the UI is divided into reusable components. Components are encapsulated, self-contained units that manage their state and handle rendering. This modular approach makes it easier to build and maintain complex UIs. Virtual DOM: React uses a virtual DOM (Document Object Model) to efficiently update and render UI compo..
