One of the many amazing things about React is that it’s more visually appealing than traditional web development frameworks like AngularJS. This might be because React favors a "simple" and "elastic" design over complex directives and components. Other factors contributing to React's visual appeal are the use of stateless components and declarative rendering. This means that instead of specifying how each component should look, you simply specify what data it needs and React will take care of the rest. In the end, it really depends on your personal taste − some people might prefer AngularJS' more polished look, while others ... Read More

DOM stands for ‘Documents Object Model’. It’s the World Wide Web Consortium's fundamental logical homepage model. Every time the UI state of an application changes, the DOM is updated to reflect the change. Whenever the application user interface is updated, the DOM is rendered which ultimately impacts the application performance, resulting in slower loading. The complexity of the DOM and the numerous UI components further depletes the performance because each change necessitates a new rendering of the page. However, the virtual DOM concept in React has changed everything. Let’s see below − What is DOM? To put it another way, ... Read More

Single Page Applications or SPAs are beginning to rule the IT marketplace now. (And for good reasons!) They are incredibly fast and render an amazing user experience. But what makes them faster? Well, the reason is that the SPAs enable the users to navigate through several pages without having to refresh the page. As the single page applications dynamically rewrite the web page content from the server, they do not load the entire web page after every render. This way, the web pages potentially improvise the performance by creating a more dynamic user experience. Let’s learn about the ... Read More

Server−side rendering has been around for a while now. It was first introduced in the early 2000s and has been used by many websites since then. The idea behind this technique is to pre−render HTML pages on a server and send them back to the client's browser as they request them. With server-side rendering (SSR), the page is rendered on the server. This ensures that the page is available to users even before it loads on their browser. We’ll get to know more about SSR in this article − How Server-side Rendering (SSR) Works? It is the process of rendering ... Read More

Every component in React has a lifecycle that incorporates several phases. Programmers usually think of this lifecycle as the component’s ‘lifetime’. The components experience the following events: Mounting, Updating, Unmounting, and Error handling. Mounting refers to the procedure of adding nodes and updating requires programmers to alter and change these nodes in the DOM. Unmounting, on the other hand, removes nodes and error handling tracks your code to ensure it works and is bug-free. These occurrences can be compared to a component's birth, development, and eventual demise. You can override multiple lifecycle methods in each React lifecycle phase to execute ... Read More
