Are you here to learn everything about React?<\/p>\n

Well, in this article I am going to tell you everything that you should know about React and its working.<\/p>\n

Let’s begin!<\/p>\n

What is React?<\/h2>\n

React is the most popular JavaScript library used to build a user interface (UI). It was created by Jordan Walke, a software engineer working at Facebook. React was first deployed on Facebook’s newsfeed and later on Instagram.com in the year 2011 and 2012 respectively.<\/p>\n

\"React\"<\/a><\/p>\n

Components act as the heart to all React applications. They are the building blocks of any React application and every React app can have multiple components. A component may have one or multiple components in its output.<\/p>\n

Practically, we write React components to write Reach applications that correspond to various interface elements. Then we have to organize these components inside higher-level components which define the structure of our application.<\/p>\n

Now let’s see, how do we use it?<\/p>\n

Did you know?<\/h2>\n

You can simply write HTML codes in JavaScript!<\/p>\n

Yes, and this is how the React works.
\nReact is a JavaScript framework and using this framework is very easy just like inserting JavaScript file in our HTML. One can then use the React exports in your application’s JavaScript.<\/p>\n

How to add React to an HTML Page?<\/h2>\n

A simple syntax to add React to a page is :<\/p>\n

<<\/span>!DOCTYPE<\/span>\u00a0html<\/span>><\/span>
\n<<\/span>html<\/span>\u00a0lang<\/span>=”en”><\/span>
\n<title<\/span>><\/span>Test React<\/span><<\/span>\/title<\/span>><\/span><\/p>\n

<!– Load React API –><\/strong><\/span>
\n<\/strong><<\/span>script<\/span>\u00a0src<\/span>= “https:\/\/unpkg.com\/react@16\/umd\/react.production.min.js”><<\/span>\/script<\/span>><\/span><\/p>\n

<!– Load React DOM–><\/strong><\/span>
\n<\/strong><script<\/span>\u00a0src<\/span>= “https:\/\/unpkg.com\/react-dom@16\/umd\/react-dom.production.min.js”><<\/span>\/script<\/span>><\/span><\/p>\n

<!– Load Babel Compiler –><\/strong><\/span>
\n<\/strong><<\/span>script\u00a0src<\/span><\/span>=”https:\/\/unpkg.com\/babel-standalone@6.15.0\/babel.min.js”><<\/span>\/script<\/span>><\/span><\/p>\n

<<\/span>body<\/span>><\/span><\/p>\n

<<\/span>script<\/span>\u00a0type<\/span>=”text\/babel”><\/span>
\n\u00a0\u00a0\u00a0\u00a0<\/span><\/strong>ReactDOM<\/span>.render<\/span>(<\/p>\n

<h1<\/span>>Hello world<\/span><\/h1<\/span>>,<\/p>\n

document<\/span>.querySelector<\/span>(‘#app’)<\/p>\n

);
\n<\/strong><\/script<\/span>><\/p>\n

<\/body<\/span>>
\n<\/html<\/span>><\/p>\n

You might see Babel in the script that may make you think more about it.<\/p>\n

Well, Babel is nothing but a JavaScript compiler that can translate markup or programming languages into JavaScript.<\/p>\n

Babel allows you to use the newest features of JavaScript.<\/p>\n

Note :<\/strong>\u00a0 To use Babel you need (<script type = “text\/babel”>)<\/span><\/p>\n

Here is an example of creating a DOM node through creating the Element function in React<\/p>\n

    \n
  1. React.createElement (“div”, { className : “blue” } , “Children Text”);<\/strong><\/li>\n
  2. React.createElement (MyCounter, { count : 4+7 } );<\/strong><\/li>\n<\/ol>\n

    Can you notice the above HTML code is very similar to the XML components?<\/p>\n

    This is really easy!<\/p>\n

    However, instead of using DOM class like in traditional method, React uses className.<\/p>\n

    Now we will see the example of React written using JSX :<\/p>\n

      \n
    1. <div className=”blue”>Children Text<\/div>;<\/strong><\/li>\n
    2. <MyCounter count={ 4 + 7} \/>;<\/strong><\/li>\n
    3. var CricketScore = {team1 : 4, team2: 5};<\/strong><\/li>\n<\/ol>\n

      <DashboardUnit data-index=”2″><\/strong><\/p>\n

      \u00a0 \u00a0 \u00a0 <h1>Scores<\/h1><Scoreboard className=”results” scores= { CricketScore } \/ ><\/strong><\/p>\n

      \u00a0 \u00a0 \u00a0 \u00a0<DashboardUnit>;<\/strong><\/p>\n

      Here,<\/p>\n

      <MyCounter> represents a “count” that shows numeric value<\/p>\n

      CricketScore is an object literal that has two prop-value pairs<\/p>\n

      <DashboardUnit> it is a block of XML that gets rendered on the page<\/p>\n

      scores= { CricketScore }: is the scores attribute that gets a value from the CricketScore object<\/p>\n

      that we have defined earlier<\/p>\n

      To make the React components easier to create, most of the part of React is written using JSX (JavaScript XML) instead of using standard JavaScript (JS).<\/p>\n

      Advantages of using React –<\/strong><\/p>\n

      React has already made its place in the upstream and is used by the number of large companies including Facebook,\u00a0 Netflix, Airbnb, DropBox, IMDb, PayPal, Tesla Motors, Walmart and hundreds of others.<\/p>\n

      Some of the reasons to use React are :<\/strong><\/p>\n

      1) It is Easy to Learn and Use :<\/strong><\/p>\n

      Anyone who holds a JavaScript background can easily learn and understand React. It can do really great things as you can easily use them in the short term. It gives you a focused solution for your UI task. It represents the V in the MVC (Model-View-Controller) pattern.<\/p>\n

      You can get its wider experience by learning through tutorials about React. There is plenty of information available in the form of how to use videos, tutorials, and data that can strengthen your learning.<\/p>\n

      2) It supports Reusable Components :<\/strong><\/p>\n

      Yes, React supports reusable components in Java, as it allows you to reuse the components that have already been developed into other applications using the same function. Each component has its own logic and controls its own rendering, so being a coder you can use them whenever and wherever you need them.<\/p>\n

      3) It is easier to write with JSX :<\/strong><\/p>\n

      As JSX is just a combination of HTML and JavaScript, you can easily write it with the JSX syntax.\u00a0 It is an optional extension that makes the entire website structure writing process much easier. This process makes easy for you to render multiple functions.<\/p>\n

      4) Virtual DOM :<\/strong><\/p>\n

      As a developer you might have struggled to create the app that has a lot of user interactions and data updates. In such a case, you have to carefully structure the app and the impact of its performance on your users. The prototype experienced directly in DOM may give users the irritating experience of your app.<\/p>\n

      Virtual DOM solves this problem. As the name is given, it is a virtual DOM, so that any changes that you make in your app first reflect on this virtual DOM, as the data lives in memory and not on your screen.<\/p>\n

      An algorithm then identifies the changes that need to be done on virtual DOM in order to identify the changes that need to be made in real DOM. This process makes sure that there is minimum update time for the real DOM, provides high performance and gives clear user experience.<\/p>\n

      5) It is SEO friendly :<\/strong><\/p>\n

      React remarkably reduces the page load time through its faster-rendering speed. It adapts the performance of the real time on the basis of current user traffic. These features are not handled by most of the frameworks available.<\/p>\n

      Conclusion –<\/strong><\/p>\n

      You might have got the insights of React from this article, where you can see that React has far better advantages over any other framework. It is very robust and can be easily adaptable by programming library. It has made its mark in the technology industry by allowing to create best looking and performing applications in order to drive the user leads and monetary sales.<\/p>\n","protected":false},"excerpt":{"rendered":"
