This enables the dynamic rendering of data, conditional rendering, and the ability to perform calculations or invoke functions directly within JSX components. Component-based Approach: JSX follows React’s component-based architecture, enabling the creation of reusable and modular UI components. These ...
Inline conditional expressions in React allow you to conditionally render elements based on certain conditions. They are used within JSX to dynamically include or exclude parts of the UI based on the evaluation of an expression. This is often achieved using the ternary operator (condition ? true...
React can also be used on the backend with technologies like Next.js, which allows for server-side rendering of React applications, blurring the line between frontend and backend to some extent. Overall, though, React is predominantly associated with frontend...
Vue.js is always developing and improving because it is relatively new to the scene. So, because of these factors, Vue.js hasn’t caught on as much as other JavaScript frameworks like Angular and React. Furthermore, most of Vue’s code has been scripted in Chinese, which causes issues fo...
It is a valuable technique for optimizing performance and memory usage in applications that deal with large datasets, complex objects, or unused resources. Read More: How to implement Lazy Loading in React Example (HTML/JavaScript Lazy Loading for Images): html In this example, the loading=”...

So React now has two Virtual DOM data structures at hand: It then runs a diffing algorithm on the two Virtual DOMs to get the set of changes between them. In our case this is going to be the difference in theclassNameproperty on the list item.Once the difference ...
The new virtual DOM is then compared with the previous one, and reconciliation occurs, resulting in the re-rendering of the component to display the data on the UI. React provides a robust foundation for building modern, scalable, and high-performance web applications. Its component-based archite...
