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...

event-driven servers, such as traditional web sites and back-end API services, but was originally designed with real-time, push-based architectures in mind. Every browser has its own version of a JS engine, and node.js is built on Google Chrome’s V8 JavaScript engine. Sounds a bit compli...
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...
React runs change detection, executes the render function that returns a new version of Virtual DOM tree. The value of the className property in this Virtual DOM version is solid. It’s very important to understand that the ***render*** function is called during each ...
