React, a popular <strong>JavaScript library<\/strong>, has revolutionized the web and <strong><a href=\"https:\/\/thecodest.co\/pl\/dictionary\/mobile-development\/\">mobile development<\/a><\/strong> landscape by providing a powerful solution for building <strong>dynamic web<\/strong> interfaces and <strong>mobile applications<\/strong>. With its extensive array of features and robust <strong>development community<\/strong>, React has become a go-to choice for developers seeking to create exceptional <strong>user interfaces<\/strong> and streamline the <strong>pace of development<\/strong>. Whether you&#8217;re building a <strong>web page<\/strong>, <strong><a href=\"https:\/\/thecodest.co\/pl\/blog\/build-future-proof-web-apps-insights-from-the-codests-expert-team\/\">web app<\/a><\/strong>, or even venturing into <strong>mobile app development<\/strong> for <strong>iOS<\/strong> and <strong>Android<\/strong>, <strong>using React<\/strong> can greatly enhance your productivity and deliver top-notch results. <\/p>\n<p>In this article, we&#8217;ll explore the <strong>pros and cons of using React<\/strong>, delve into its versatile set of features, and analyze how it can transform your <strong>web and mobile<\/strong> application <a href=\"https:\/\/thecodest.co\/pl\/blog\/how-the-codests-team-extension-model-can-transform-your-in-house-development-team\/\">development process<\/a>.<\/p>\n<p>Here are some retrieving statistics regarding <strong>React<\/strong> that are worth to know: <\/p>\n<ul>\n<li>\n<p>According to Stackoverflow Developer Survey (2021) above 40% of developers have chosen <strong><a href=\"https:\/\/thecodest.co\/pl\/blog\/hire-react-js-developer\/\">React.js<\/a><\/strong> as most <strong>popular web framework<\/strong>.<\/p>\n<p><img decoding=\"async\" src=\"\/app\/uploads\/2024\/05\/zrzut-ekranu-2022-05-26-o-10.15.00.png\" alt=\"Stackoverflow survey statistic\" title=\"most popular framework according to stackovewflow survey \" \/><\/p>\n<\/li>\n<li>\n<p>Also, we can see raw fact that <strong>React<\/strong> is the most downloaded package from npm.<\/p>\n<p><img decoding=\"async\" src=\"\/app\/uploads\/2024\/05\/image.png\" alt=\"graph react downloads\" title=\"React downloads popularity \" \/><\/p>\n<\/li>\n<\/ul>\n<h2> Pros of React from business perspective<\/h2>\n<h3> Easy to find great developers<\/h3>\n<p>\u200b<br \/>\nBecause of <strong>React<\/strong> popularity, there is a huge amount of <strong>React developers to hire<\/strong>. It makes that it is<br \/>\nmuch simpler to find skilled <strong><a href=\"https:\/\/thecodest.co\/pl\/dictionary\/react-developer\/\">React developer<\/a><\/strong> with wide specialistic knowledge rather than in other technologies with the smaller <a href=\"https:\/\/thecodest.co\/pl\/dictionary\/what-is-the-size-of-your-potential-reachable-market\/\">market<\/a> (like <a href=\"https:\/\/thecodest.co\/pl\/blog\/hire-vue-js-developers\/\">Vue<\/a>).<\/p>\n<h3>Creating cross-platform products<\/h3>\n<p>\u200b<br \/>\nThat is a crucial point if we speak about clients who want to build cross-platform products &#8211; especially small companies. <strong>React<\/strong> gives us the ability to easily create web apps, but we have<br \/>\nalso <a href=\"https:\/\/reactnative.dev\/\" rel=\"nofollow\">React-Native<\/a> with which we can develop applications for<br \/>\nAndroid and iOS writting <a href=\"https:\/\/thecodest.co\/pl\/dictionary\/what-is-code-refactoring\/\">code<\/a> in [React.js] (https:\/\/thecodest.co\/blog\/what-is-react-js-and-why-is-it-framework-so-popular\/) with same syntax as for web, the only thing that<br \/>\nchanges these are mobile specific components. It significantly reduces clients costs,<br \/>\nbecause client doesn&#8217;t have to hire many kinds of developers like React for web, <a href=\"https:\/\/thecodest.co\/pl\/blog\/top-programming-languages-to-build-e-commerce\/\">Java<\/a> for<br \/>\nAndroid and Swift for iOS &#8211; instead he needs only <strong>React developers<\/strong>.<\/p>\n<h3>Quick development<\/h3>\n<p>\u200b<br \/>\nThis point is more for startups and total MVPs. <strong>React developers<\/strong> can write complex code, with high abstraction, <a href=\"https:\/\/thecodest.co\/pl\/dictionary\/typescript-developer\/\">TypeScript<\/a> etc., but <strong>React<\/strong> lets us also write code swiftly without large boilerplate and many tricky libraries. It is valuable when we want to build a small <a href=\"https:\/\/thecodest.co\/pl\/dictionary\/how-to-build-an-mvp\/\">MVP<\/a> app in a short time.<\/p>\n<h2>Pros of React from developer perspective<\/h2>\n<h3>Large community<\/h3>\n<p>\u200b<br \/>\nIn commercial development, one the most important things when we choose to use our libraries, tools, etc. If a certain technology has a lot of fans it facilitates and speeds up the development process. When you face any bug, then you can ask on a public forum and there is a high<br \/>\nthe probability that among millions of <strong>React developers<\/strong> some of them solved this bug before.<br \/>\nThanks to our large community we also have tons of <strong>React<\/strong> 3-rd party libraries, tutorials, and events.<\/p>\n<h3>Backward compatibility<\/h3>\n<p>\u200b<br \/>\nThat is one of the best things in <strong>React<\/strong>, that it doesn&#8217;t do <b>breaking changes<\/b>. After every<br \/>\nupdate, React <a href=\"https:\/\/thecodest.co\/pl\/blog\/compare-staff-augmentation-firms-that-excel-in-api-team-staffing-for-financial-technology-projects\/\">API<\/a> stays almost the same. Even if they are going to do any bigger change, you are going to see warnings for a long time, so you can easily migrate your code.<\/p>\n<h3>Reusable components<\/h3>\n<p>\u200b<br \/>\n<strong>React developers<\/strong> are able to create reusable components. It lets the developers create small<br \/>\npieces of UI and include them in any place of the application. You can combine many smaller components to create a bigger, complex UI. It is quite often the case when developers build an app using ready UI components, fo ex. MaterialUI.<\/p>\n<h3>Complete SSR\/SSG frameworks<\/h3>\n<p>\u200b<\/p>\n<ul>\n<li><strong>SSR<\/strong> &#8211; Server Side Rendering<\/li>\n<li><strong>SSG<\/strong> &#8211; Server Side Generator<\/li>\n<\/ul>\n<p>\u200b<br \/>\nIn the programming world, many technologies have been built based on <strong>React<\/strong>. Among all<br \/>\nthese things, we have frameworks that let us build <strong>React apps<\/strong> rendered by a server or just<br \/>\ngenerate html files based on the <strong>React code<\/strong>. An SSG example is <a href=\"https:\/\/www.gatsbyjs.com\/\" rel=\"nofollow\">Gatsby<\/a> which makes generating fast and SEO-friendly websites in <strong>React<\/strong> straightforward. Another useful framework is <a href=\"https:\/\/nextjs.org\/\" rel=\"nofollow\">Next.js<\/a> \u2013 with it we<br \/>\nhave SSG advantages and also the ability to create pages rendered in <strong>React<\/strong> by a server,<br \/>\nwhich makes it easier to create dynamic and SEO-friendly web apps.<\/p>\n<h3>Virtual DOM<\/h3>\n<p>\u200b<br \/>\n<b>Virtual DOM (Document Object Model)<\/b> &#8211;  is responsible for keeping the <strong>React app<\/strong> abstraction and synchronizing up-to-date with the real DOM (it is what we really see on our<br \/>\ndisplay). It lets you improve app performance and speed because <b>React Virtual DOM<\/b> implementation compares app abstraction between changes and re-renders only the changed parts of the app.<\/p>\n<h2>Cons of React<\/h2>\n<p>\u200b<\/p>\n<h3>View mixed with logic by default<\/h3>\n<p>\u200b<br \/>\nIn <strong>React<\/strong>, we don&#8217;t have separated component logic and view by default (like it is in Angular). Instead, our component contains a function `render` which returns JSX (syntax similar to<br \/>\nhtml to describe views). That is a disadvantage, as because of it we can meet components(mostly legacy) where we can see hundreds of mixed lines of logic code and jsx (view) code. <\/p>\n<p>It makes code reading more difficult and you often have to jump between particular lines in the file. There was an &#8216;invented&#8217; simple pattern to solve it: <b>Smart and Dumb components<\/b>. In brief, <b>Smart<\/b> components are responsible for components logic, but<br \/>\n<b>Dumb<\/b> components are just presentational components that handle displaying <a href=\"https:\/\/thecodest.co\/pl\/blog\/app-data-collection-security-risks-value-and-types-explored\/\">data<\/a> in jsx. But still, it is some kind of a pattern, not any standard or rule imposed by <strong>React<\/strong>, so<br \/>\n<strong>JS developers<\/strong> don&#8217;t  always follow it.<\/p>\n<h3> React apps are based on 3rd party libraries<\/h3>\n<p>\u200b<br \/>\nIt is both an advantage and a disadvantage. React is <em>&#8216;just a library&#8217;<\/em> and there are no official<br \/>\nlibraries to handle common features in frontend applications, like ex. routing, http requests, etc. It is an advantage because you have freedom and if you are an aware <strong>JS developer<\/strong>, you can<br \/>\nselect the best tools for your needs. Also it is a disadvantage because React doesn&#8217;t have many base tools out of the box. Even if you use only the most popular and the most common libraries, you may experience <strong>React<\/strong><br \/>\nversions conflict between the library version and your <strong>React<\/strong> app version (it is mostly about<br \/>\nlegacy apps). <\/p>\n<p>If you want to keep your app up-to-date with the <strong>React version<\/strong>, keep in mind that it may require an update of also 3rd party libraries that live their own lives. Just as<br \/>\n<strong>React<\/strong> has great backward compatibility, some libraries (even very popular ones) may<br \/>\nexperience some breaking changes.<\/p>\n<h3>No convention<\/h3>\n<p>\u200b<br \/>\n<strong>React<\/strong> doesn&#8217;t impose any development conventions. It takes longer to introduce new<br \/>\ndevelopers to a legacy project because very often <strong><a href=\"https:\/\/thecodest.co\/pl\/blog\/how-to-find-the-best-team-of-javascript-software-developers\/\">JavaScript developers<\/a><\/strong> <strong>create React apps<\/strong> in<br \/>\ndifferent ways and there is a high probability that you will face a legacy project with coding<br \/>\nconventions you haven&#8217;t seen in <strong>React<\/strong> before. It forces the development <a href=\"https:\/\/thecodest.co\/pl\/dictionary\/how-to-lead-software-development-team\/\">team<\/a> to spend time on discussing some common development rules in a project. When the team changes many<br \/>\ntimes, it may result in a messy code because everyone has different habits and follows different conventions.<\/p>\n<h2>Conclusions<\/h2>\n<p>\u200b<br \/>\nPopularity, large community, huge number of packages and the whole ecosystem makes <strong>React<\/strong> a very solid and strong framework nowadays. Summing it up from the perspective of developer, I wouldn&#8217;t say that React is better or worse than any other <strong>popular JavaScript framework<\/strong>. All of them have some advantages and disadvantages, but finally it depends on which one suits you better.<\/p>\n<p>But from the perspective of a business owner, I would say that <strong>React<\/strong> is definitely better than<br \/>\nthe rest of the stuff on the market, mostly because of a large number of developers, a lot of packages made for much different business and use cases developed by the biggest a community which makes development easier and faster.<\/p>\n<p>In conclusion, React offers a comprehensive <strong>development framework<\/strong> that empowers <strong>web developers<\/strong> and <strong>mobile app<\/strong> creators to craft cutting-edge applications with ease. Its extensive ecosystem, including <strong>React Developer Tools<\/strong> and an abundance of reusable <strong>React components<\/strong>, simplifies the <strong>development process<\/strong> and accelerates the pace of creating user interactions and component states. By leveraging React&#8217;s capabilities, businesses can deliver dynamic web and <strong>mobile interfaces<\/strong> while enjoying the benefits of code reusability and streamlined development practices. Despite some limitations, such as <strong>SEO handling<\/strong> and the need for <strong>JavaScript extensions<\/strong> for certain functionalities, React remains a powerful choice for building <strong>web interface<\/strong>s and <strong>mobile applications<\/strong>. With its robust development community and continuous evolution, React continues to shape the future of <strong>web and mobile development<\/strong>, making it a compelling choice for <strong>web developers<strong>, <strong>mobile app<\/strong> creators, and business owners alike.<\/p>\n<p>If you are struggling with finding <strong>JavaScript developers<\/strong> make sure to check our article on that topic <a href=\"https:\/\/thecodest.co\/blog\/how-to-find-the-best-team-of-javascript-software-developers\">here<\/a>.<\/p>\n<p><a href=\"https:\/\/thecodest.co\/contact\"><img decoding=\"async\" src=\"\/app\/uploads\/2024\/05\/interested_in_cooperation_.png\" alt=\"cooperation banner\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dlaczego warto korzysta\u0107 z React?
