Stay with us until the end of this article to answer all your questions.<\/span><\/p>\n<h2><strong><span data-preserver-spaces=\"true\">What is React?<\/span><\/strong><\/h2>\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">React is an open-source JavaScript library for building fast, interactive\u00a0<strong>user interfaces for mobile,<\/strong>\u00a0<strong>web,<\/strong>\u00a0and\u00a0<strong>one-page applications<\/strong> (SPAs). It manages the View layer, which is responsible for the program&#8217;s appearance in the <a href=\"https:\/\/ded9.com\/all-about-mvc-site-design\/\">MVC<\/a> architecture.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">The central part of React apps is the components, and each piece is a combination of <a href=\"https:\/\/en.wikipedia.org\/wiki\/HTML\" target=\"_blank\" rel=\"noopener\">HTML<\/a> and JavaScript, each representing a small part of a more extensive UI.<\/span><span data-preserver-spaces=\"true\">\u00a0To better understand this, let&#8217;s take a look at an Instagram page:<\/span><\/p>\n<h4><span data-preserver-spaces=\"true\">Components in React\u00a0<\/span><\/h4>\n<p>In React, each user interface element is a component. Each piece can have other parts as output, and this framework also creates reusable user interface components.<\/p>\n<h2><strong><span data-preserver-spaces=\"true\">React History<\/span><\/strong><\/h2>\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">React was created by a Facebook software engineer named\u00a0<strong>Jordan Walke<\/strong>. The first version was used on Facebook in 2011 and then on Instagram in 2012. Finally, in 2013, this library became open-source, which many web developers have considered.<\/span><\/p>\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">Now that we understand React, we can move on to &#8221;\u00a0<strong>Why React is the Most Popular JavaScript Library for Web Application Development.<\/strong> &#8220;<\/span><\/p>\n<h2><strong><span data-preserver-spaces=\"true\">Why should we learn ReactJS?<\/span><\/strong><\/h2>\n<p>The main question that may arise for any developer is why we should use React. There are so many frameworks and open-source libraries for developing front-end and web applications, so what is the reason for React&#8217;s superiority that makes you want to learn it?<\/p>\n<p><span data-preserver-spaces=\"true\">Since it is tough to spend time learning new technologies, and mostly\u00a0<\/span><strong><span data-preserver-spaces=\"true\">the lifespan of front-end technologies is short,<\/span><\/strong><span data-preserver-spaces=\"true\">\u00a0and you can not risk enough to learn a new technology, you should look for a technology that is the best in its field and type. And it&#8217;s worth the risk that I suggest you\u00a0<\/span><strong><span data-preserver-spaces=\"true\">React<\/span><\/strong><span data-preserver-spaces=\"true\">. In the following, we will examine the reasons for this choice.<\/span><\/p>\n<h3><strong><span data-preserver-spaces=\"true\">Simplicity<\/span><\/strong><\/h3>\n<p><span data-preserver-spaces=\"true\">React makes it easy to create dynamic web applications because it requires less coding and performs better. The library uses a particular grammar structure called\u00a0<\/span><strong><span data-preserver-spaces=\"true\">JSX<\/span><\/strong><span data-preserver-spaces=\"true\">\u00a0that allows developers to combine HTML and\u00a0<\/span><strong><span data-preserver-spaces=\"true\">JavaScript<\/span><\/strong><span data-preserver-spaces=\"true\">.<\/span><\/p>\n<p>JSX is not necessary for templating, and programmers can work with JavaScript. However, once you use JSX, you will no longer use JavaScript for templating.<\/p>\n<h3><strong><span data-preserver-spaces=\"true\">Easy to learn<\/span><\/strong><\/h3>\n<p><span data-preserver-spaces=\"true\">React concepts are easy to understand and learn. Anyone with a brief HTML, CSS, and JavaScript background can quickly learn this library. Learning other technologies, such as AngularJS and Ember.js, from one Domain Specific Language is much harder to use.<\/span><\/p>\n<h3><strong><span data-preserver-spaces=\"true\">Function<\/span><\/strong><\/h3>\n<p><span data-preserver-spaces=\"true\">React uses a\u00a0<\/span><strong><span data-preserver-spaces=\"true\">virtual DOM<\/span><\/strong><span data-preserver-spaces=\"true\">\u00a0that makes creating web applications faster. Instead of updating all the components, it compares the previous elements and updates only the ones in the actual DOM.<\/span><\/p>\n<h3><strong><span data-preserver-spaces=\"true\">Reusable components<\/span><\/strong><\/h3>\n<p><span data-preserver-spaces=\"true\">Components are the building blocks of any React program, and each program consists of several components. Using React, we can design multiple components and reuse them, significantly reducing program development time.<\/span><\/p>\n<h2><strong><span data-preserver-spaces=\"true\">ReactJS Library Learning Prerequisites<\/span><\/strong><\/h2>\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">As mentioned before, React is a JavaScript library. So, of course, you have to be familiar with JavaScript to start learning it. Since JavaScript has versions\u00a0<strong>ES6<\/strong>\u00a0to\u00a0<strong>ES11,<\/strong> and new features have been added in each version, it is better to work with at least version 6, in addition to being familiar with\u00a0<strong>ECMAScript5<\/strong>.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">But you may be wondering how much JavaScript I need to know? It can be said that there is no exact answer to this question, but we can say that the more you work with JavaScript and JavaScript projects, the more ready you can enter the field of working with ReactJS. In other words, the learning path is smoother for you, and you can become a rehab specialist in a shorter period.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">In general, to get started with React, you need to be familiar with the following concepts:<\/span><\/p>\n<ul>\n<li><span data-preserver-spaces=\"true\">Introduction to JavaScript<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Familiarity with programming concepts such as objects, functions, arrays, and classes<\/span><\/li>\n<li><span data-preserver-spaces=\"true\">Relative familiarity with\u00a0<\/span><strong><span data-preserver-spaces=\"true\">HTML<\/span><\/strong><span data-preserver-spaces=\"true\">\u00a0and\u00a0<\/span><strong><span data-preserver-spaces=\"true\">CSS<\/span><\/strong><\/li>\n<li><span data-preserver-spaces=\"true\">Basic familiarity with npm<\/span><\/li>\n<\/ul>\n<h3><strong><span data-preserver-spaces=\"true\">Testability<\/span><\/strong><\/h3>\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"><span data-preserver-spaces=\"true\">React JS <\/span>can <strong>check the components, functions, and parameters with the desired states and outputs,<\/strong>\u00a0which is a positive feature that\u00a0<strong>increases accuracy<\/strong>\u00a0and\u00a0<strong>saves<\/strong> time.<\/span><\/p>\n<h3><strong><span data-preserver-spaces=\"true\">JavaScript Native approach to web and mobile application development<\/span><\/strong><\/h3>\n<p><span data-preserver-spaces=\"true\">React Native is based on JavaScript and React, and all React features apply to React Native. Using React, you can create Native applications for\u00a0<\/span><strong><span data-preserver-spaces=\"true\">iOS<\/span><\/strong><span data-preserver-spaces=\"true\">\u00a0and\u00a0<\/span><strong><span data-preserver-spaces=\"true\">Android operating systems.\u00a0<\/span><\/strong><span data-preserver-spaces=\"true\">The code written for these two operating systems is standard, and you can use the written components in several projects.<\/span><\/p>\n<p>You may be interested to know that you use React apps every day while checking your emails, watching your favorite TV shows, or even checking social media. In this section, we will introduce you to some companies that have used this technology.<\/p>\n<ul>\n<li><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">Facebook is one of the most popular social networks for sharing photos, videos, and other content.
