Moreover, the rich ecosystem around this JavaScript library offers flexibility in creating stable, immersive, and scalable websites.<\/p>\n<p>The React team adds new features (which we will elaborate soon) to better manage complexity among UI elements, create smooth interfaces, and update its algorithms for fluid animations and gestures.<\/p>\n<p>In the <a href=\"https:\/\/survey.stackoverflow.co\/2022\/\" target=\"_blank\" rel=\"noopener\">Stack Overflow Data Survey 2022<\/a>, from 58,743 responses, 42.62% of professional developers opt for React as a web framework. Without a doubt, social proof for React is trustworthy and reliable.<\/p>\n<p>Each of us has experienced blazing-fast and pixel-perfect interactive User Interfaces on Facebook, Uber, Netflix, and many others. It\u2019s pretty natural to wonder why React is preferred for web development and apps? And no doubt, you also want to create such web and app experiences for your users.<\/p>\n<p>So, the motivation for this blog is to:<\/p>\n<ul>\n<li>present a high-level overview of React&#8217;s design principles.<\/li>\n<li>Show what you can achieve with it for your web apps.<\/li>\n<\/ul>\n<p>Before we move on, it is essential to remember that React is only a library for building User Interfaces and not a whole framework. This distinction will help you not over-indulge and acknowledge that it is not a magic solution.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_innovative_algorithm_to_update_UI_elements_swiftly\"><\/span>The innovative algorithm to update UI elements swiftly.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most of the single web applications were slow because updating UI elements using earlier methods was inefficient. UI elements are buttons, forms, layouts, sections like the news feed on Twitter, checkboxes, etc.<\/p>\n<p>The traditional rendering method to update changes in the DOM (Document Object Model) manipulation was expensive. Even simple frequent changes from scrolling, toggling, etc, contributed to abrupt interactions. Technically, earlier methodologies had to deal with O(n3) complexity.<\/p>\n<p>React&#8217;s team solved this issue by designing the Diff algorithm, which heuristically, in fewer steps, updates, or renders UI elements. This process is <a href=\"https:\/\/reactjs.org\/docs\/reconciliation.html\" target=\"_blank\" rel=\"noopener\">reconciliation<\/a>. Virtual DOM is another name for this concept.<\/p>\n<p>With Virtual DOM, only those components that have changed are updated in the real DOM rather than re-rendering the whole DOM tree iteratively. It thus helps in creating fast, dynamic websites.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Virtual_DOM_to_React_Fiber\"><\/span>Virtual DOM to React Fiber<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As said, React&#8217;s team keeps on working to refine the user experience. Though Virtual DOM is fast yet it has its limitations. Virtual DOM is synchronous, i.e. there is no way to prioritize tasks. Prioritizing work is always a sound strategy. Isn&#8217;t it?<\/p>\n<p>Examples of high-priority work may be the user&#8217;s need for immediate feedback when it clicks or types, auto-complete suggestions, etc. In comparison, low-priority work may be calculating the number of likes from the server.<\/p>\n<\/div>\n<p>But Since you can&#8217;t delay low-priority work that may be data-intensive with Virtual DOM, users would have a jarring experience interacting with UI elements.<\/p>\n<div class=\"blog_layout\">\n<p>And therefore, React Fiber was introduced in <a href=\"https:\/\/github.com\/acdlite\/react-fiber-architecture\" target=\"_blank\" rel=\"noopener\">React 16<\/a>\u00a0to perform incremental rendering and scheduling. Since then, it has been the default reconciler. It enhances the perceived performance, thus eliminating even the slightest unresponsiveness.<\/p>\n<p>Lin Clark, the developer behind <a href=\"https:\/\/code-cartoons.com\/\" target=\"_blank\" rel=\"noopener\">code-cartoons.com<\/a>, explained quite simply what React Fiber does-It teaches how to do effective project management to the main thread.<\/p>\n<p>React Fibre makes it possible to split, prioritize, abort, or resume tasks to improve the rendering of animations and gestures.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Independent_and_reusable_components\"><\/span>Independent and reusable components<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/netmaxims.com\/blog\/wp-content\/uploads\/2022\/05\/whyreact-building-blocks.jpg?w=750&#038;ssl=1\" \/><\/p>\n<p>What are React Components? It can be a navbar, table, chat window, news feed, comment section, etc. A highly interactive website like Facebook has more than 50k+ components. So what is the idea behind the components-based approach?<\/p>\n<p>The design principle document of React mentions the composition of components as a significant feature. The components in React are isolated, immutable, and independent. It means that change in one component won&#8217;t affect other components. Managing and visualizing UI then is intuitive.<\/p>\n<p>Another handy feature of components in React is that they are reusable. For us, who are concerned with the rapid development, it allows reusing the components without writing them again. And even utilize components created by other developers.<\/p>\n<p>Walmart contains many brands and has numerous branches. So, their UI elements like forms, navigation bars, etc., must be consistent. Also, they didn&#8217;t desire any duplicity of code. The reusability of UI components was the solution to their problem. Hence, they opted for React as its front-end development tool.<\/p>\n<p>In the context of Facebook, developers can create multiple chat windows using reusability and unidirectional flow of data, i.e. movement of data from top to bottom only. Because of it changes in one chat window won&#8217;t affect other chat windows or overall UI.<\/p>\n<p>Components in React are reusable and follow a unidirectional pattern. The simple benefit of this design principle is systematic scalability and easy data flow prediction.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Isomorphism_for_performance_and_SEO\"><\/span>Isomorphism for performance and SEO.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Isomorphism in web development means using both client-side and server-side for rendering. The React allows the usage of isomorphism to speed up the performance. You must emphasize fast loading when your audience is on multiple devices and uses varied networks.<\/p>\n<p>The Walmart and Twitter research team found that the fast loading of the first page or landing page enhances the user experience. In fact, Time-to-Interactive is a more helpful <a href=\"https:\/\/netmaxims.com\/blog\/website-performance-metrics\/\" target=\"_blank\" rel=\"noopener\">website performance metric<\/a> to follow than the loading page metric. Decreasing delay in response to interactions even by seconds results in excellent user engagement.<\/p>\n<p>Netflix using isomorphic React optimized its performance past the sign-up page. Actually, it was one of the crucial reasons for their developers&#8217; team to choose React, besides the component approach and Virtual DOM concept. Also, they solved their network latency issue with React. I enjoyed reading &#8216;<a href=\"https:\/\/netflixtechblog.com\/netflix-likes-react-509675426db\" target=\"_blank\" rel=\"noopener\">Netflix like React<\/a>&#8216; blog and recommend it.<\/p>\n<p>Fast loading and quick response to interaction with elements directly impact SEO. Furthermore, server-side rendering (SSR) makes it easy to crawl websites. Because with SSR, web apps load and become interactive in no time. As a result, Google bots can crawl your web pages fast and reduce the crawl budget. At the end of the article, I mentioned how React has revamped server-side rendering in its recent update.<\/p>\n<p>It is fascinating how React comes up with new ideas to make the web experience smoooooth!<\/p>\n<p>If you are looking for an experienced <a href=\"https:\/\/netmaxims.com\/website-development\/\" target=\"_blank\" rel=\"noopener\">website development company<\/a>. In that case, I assure you, my team enjoys participating in complex and unique <a href=\"https:\/\/netmaxims.com\/our-portfolio\/\" target=\"_blank\" rel=\"noopener\">web and app projects<\/a>.<\/p>\n<p>We love delivering addictive user experiences (in a positive sense, of course, we don&#8217;t want to indulge in <a href=\"https:\/\/netmaxims.com\/blog\/what-we-have-learned-in-web-development-after-18-years-part-1-dont-make-dark-patterns\/\" target=\"_blank\" rel=\"noopener\">evil design patterns<\/a>).<\/p>\n<p>Anyways, I stumbled upon a nice statement. It goes something like-\u2019Software testers go to heaven\u2019. On that note, let&#8217;s talk about testing.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Test_and_test_more\"><\/span>Test, and test more.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/netmaxims.com\/blog\/wp-content\/uploads\/2022\/05\/whyreact-testing.jpg?w=750&#038;ssl=1\" \/><\/p>\n<p>You know the significance of testing to find bugs and faults in any app, software, or website. So, how helpful is React when it comes to testing? Simply put, it provides all the resources for debugging and maintaining the stability of the codebase.<\/p>\n<p>But to give more authority to this claim. I will provide examples of two successful tech companies-Netflix and Asana.<\/p>\n<p>Netflix rigorously performs A\/B testing to validate design and performance and ensure that the changes are based on real-world data rather than assumptions. Its UI engineers make use of the Component-based approach to test and maintain the code of many variations of UI and discard versions that do not increase performance.<\/p>\n<p>Asana is a work management system that runs on mobile and the web. Its UI engineers are obsessive about performance. When they were designing new tour guides, they also benefited from the modular approach taken by React for building UI. They were better able to mitigate risks and form a clear path for adding and experimenting with new features in the future.<\/p>\n<p>Additionally, Error Boundaries are components introduced in React 16 to find errors in the respective child component tree. Developers can use ReactDev Tools and Jest, a testing framework, for practical and easy debugging.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Easy_migration_and_seamless_integration_with_other_libraries\"><\/span>Easy migration and seamless integration with other libraries.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Interoperability is another design principle mentioned in the official document of React. This feature helps companies migrate to React without much hassle and deploy React when necessary.<\/p>\n<p>Facebook extensively uses server-side systems (XHP) and many UI libraries besides React. It glaringly shows React is flexible enough to work coherently with other powerful <a href=\"https:\/\/netmaxims.com\/blog\/11-on-demand-usable-web-development-tools\/\" target=\"_blank\" rel=\"noopener\">web development tools<\/a>.<\/p>\n<p>Asana&#8217;s team observed that almost 99% of users skip product tours. It was evident that they needed to design new product tours for better engagement. They were using Luna1, and it was difficult to add features.<\/p>\n<p>But UI engineers didn&#8217;t want to scrap Luna1 abruptly. They chose React as you can sprinkle code using it with existing tech and gradually migrate to manage risks.<\/p>\n<p><a href=\"https:\/\/netmaxims.com\/blog\/examples-of-websites-built-using-react\/\" target=\"_blank\" rel=\"noopener\">Examples of React websites<\/a> to convince you about the Interoperability feature.<\/p>\n<ul>\n<li>Tinder used React for UI and Redux for state management.<\/li>\n<li>Flamingo, a women&#8217;s body care brand, coupled React with Gatsby for server-side rendering. As a result, page loading got five times faster.<\/li>\n<li>ElizabethWarren.com moved completely from WordPress for better performance using Redux.<\/li>\n<li><a href=\"https:\/\/netmaxims.com\/blog\/react-native-app-development-outlining-eminence\/\" target=\"_blank\" rel=\"noopener\">React Native<\/a> to build mobile apps.<\/li>\n<\/ul>\n<p>Popular libraries that enhance the performance, stability, and effectiveness of React.js:<\/p>\n<ul>\n<li><a href=\"https:\/\/reactrouter.com\/\" target=\"_blank\" rel=\"noopener\">React Router<\/a> for client-side routing.<\/li>\n<li><a href=\"https:\/\/redux.js.org\/\" target=\"_blank\" rel=\"noopener\">Redux<\/a> for state management.<\/li>\n<li><a href=\"https:\/\/www.npmjs.com\/package\/react-motion\" target=\"_blank\" rel=\"noopener\">React Motion<\/a> for animation.<\/li>\n<li><a href=\"https:\/\/jestjs.io\/\" target=\"_blank\" rel=\"noopener\">Jest<\/a> for testing.<\/li>\n<li><a href=\"https:\/\/mui.com\/\" target=\"_blank\" rel=\"noopener\">Material UI<\/a> for User Interfaces.<\/li>\n<li><a href=\"https:\/\/github.com\/facebookarchive\/react-360#:~:text=React%20360%20is%20a%20framework,through%20a%20variety%20of%20devices.\" target=\"_blank\" rel=\"noopener\">React 360<\/a> for creating virtual experiences.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"State_Management_for_scalability\"><\/span>State Management for scalability.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/netmaxims.com\/blog\/wp-content\/uploads\/2022\/05\/whyreact-scalability.jpg?w=750&#038;ssl=1\" \/><\/p>\n<p>In React, State is an object that holds information about the component. The component&#8217;s state changes when the user interacts with it. There is frequent and numerous change in state in any current dynamic website.<\/p>\n<p>If there is no efficient and fast way to manage changes, you know how your users will treat you.<\/p>\n<p>Let us take as an example an e-commerce website. There are too many components-check-out, add to cart, save for later, quantity, etc in a typical eCommerce site. A change in the state of one component has a rippling effect as other logical components&#8217; states need to change. Therefore, you need a tool for robust scaling and handling complexity.<\/p>\n<p>While developers can use classes for state management, React introduced Hooks onwards React 16.8 for state management. With hooks, there is no need to write classes.<\/p>\n<p>But why Hooks?<\/p>\n<blockquote><p>Classes confuse both machines and humans-A critical insight mentioned in the official React documentation.<\/p><\/blockquote>\n<p>Additionally, it is easy to separate logic from UI when using Hooks. It helps in better shareability of components as the extracted logic state is independent and reusable.<\/p>\n<p>Did you notice the pattern? The React team introduces abstractions to help developers think and manage UI intuitively and more humanly.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"React_18_new_features_to_display_content_intelligently\"><\/span>React 18 new features to display content intelligently.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>React released its most updated version in March 2022. The new features introduced are Concurrent Rendering, Automatic Batching, and Transitions.<\/p>\n<p>Covering all the aspects of <a href=\"https:\/\/reactjs.org\/blog\/2022\/03\/29\/react-v18.html\" target=\"_blank\" rel=\"noopener\">React v18.0<\/a> is beyond the scope of the current blog. Hence, I will give a high-level understanding of only concurrent rendering. It will help you understand how rendering affects user engagement.<\/p>\n<p>Pre-React 18, rendering was non-interruptible. It involved fetching data, loading JavaScript, and rendering an entire application. Users could not immediately interact with websites because only static HTML was rendered when websites were content-heavy.<\/p>\n<p>Concurrent rendering aims to upgrade the server-side performance of React so that users can interact with the helpful content almost immediately.<\/p>\n<p>It does so with the help of <a href=\"https:\/\/youtu.be\/pj5N-Khihgc\" target=\"_blank\" rel=\"noopener\">Suspense<\/a>, a React component that allows prioritizing the rendering of different UI elements.<\/p>\n<p>Suppose, your web page has a navbar, profile, and comment components. Making the comment component fully interactive is a data-intensive task. With the help of Suspense, you can delay the rendering of the comment component but prioritize the rendering and interactivity of the navbar and profile.<\/p>\n<p>The users perceive high performance because they can immediately interact with other elements of the webpage and not stare at the static or blank website.<\/p>\n<p>Now, suppose the user clicks on the comment section. In that case, React will begin loading the comment component and pause the rendering of other elements as they are currently low-priority tasks.<\/p>\n<p>So with React 18, significant improvements are made in the architecture to provide a more engaging experience to the users.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"React_is_not_a_magic_solution\"><\/span>React is not a magic solution.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>By now, understanding how React works and why major tech companies have adopted React, you may deduce that React will solve all your web development issues. Or it will magically create a high-performing website.<\/p>\n<p>This section wishes to show some red flags so that you don&#8217;t cultivate any incorrect view of React.<\/p>\n<p>First, overusing React can downgrade your performance. React is designed as a UI library and not a complete framework. Many developers use too many components for UI even when it is not required. It leads to undesired complexity and an unmanageable codebase.<\/p>\n<p>Since reusability and modularity are design concepts, experienced developers must harness these concepts in a balanced way.<\/p>\n<p>As said, overusing React affects performance. Netflix discarded React for logged-out pages and sign-up pages. Instead, they wrote in Vanilla JS and prefetched and observed betterment in Time-To-Interactive metrics.<\/p>\n<p>Our <a href=\"https:\/\/netmaxims.com\/website-development\" target=\"_blank\" rel=\"noopener\">web development services<\/a> will assist you in choosing the best stack for your web development project.
