Are you a novice developer wondering why ReactJS is popular? Read on to understand what React is, its growing popularity, and why you should use it.

  1. What is React and How does it Work?

    Why use react

    React is a popular JavaScript (JS) library for web and mobile application development. Originally built by Facebook, React has an assortment of recyclable JS code particles ideal for developing UI (user interface), also known as components. ReactJS is not a JS framework. That is because it only facilitates the rendering of an application’s display layer components.

    Many JavaScript front-end developers combine React with frameworks such as Vue and Angular to form complex operations. React helps illustrate the relevant document structure and outlines how documents are accessed and handled. React leverages a virtual Document Object Model (DOM) in JavaScript.

    Every time it wants to write or read to the document object model, it utilizes its virtual depiction. The virtual DOM then attempts to upgrade the browser’s DOM most methodically to pair with the React components. This is because JavaScript is swift and having a DOM tree inside it accelerates its manipulation. While building browser DOM components can be a daunting task, React components are simple and cost-friendly to create fundamental elements.

    Initially, React was designed to be browser-based. However, following continued innovations and advancements, it can be used with Node.JS in a server. React does not shape the browser’s document object module directly. Instead, it builds a virtual DOM memory where it executes all the necessary manipulation before incorporating the changes in the browser DOM. React determines any applied changes before making the ideal modifications.

Due to ReactJS’ credibility, many people are now interested in using it.

    • Is React Front-End or Backend?

      React is a popularly used Library that facilitates front-end development. It allows developers to operate with a virtual browser which more user-friendly.

    • Is React Hard to Learn?

      Are you just venturing into the development? Learning React will not be easy. You will first need to be conversant with the basics of JavaScript, programming, CSS, and HTML before attempting to learn React. Gaining proficiency in React could take you between one to twelve months based on your existing knowledge and experience in software development. Apart from knowing the basics of web development, the other stages of learning React are:

      • Configuring a React application
      • Developing your inaugural prototypes
      • Being conversant with React and its environment.

      People with prior experience in software development will have an easier time learning React.

    • What is React Mainly Used For?

      ReactJS is an open-source, multi-purpose library, mainly used in front-end development targeting the configuration of user interfaces. Companies can use React in:

      • Creating SPAs (single-page applications). React can rewrite and amend web page content without refreshing the page.
      • To facilitate front-end development requirements on social media websites
      • Creating native mobile applications

      Some big corporations like SalesForce, Netflix, and the New York Times use React to develop their mobile applications.

  3. Why do developers prefer React?

    ReactJS allows developers to build better user interface applications to boost user experience. Companies that choose React are guaranteed a more enhanced performance. Here are various reasons why developers choose React over other libraries. Through ReactJS, developers can write their applications inside JavaScript.

    JavaScript Syntax Extension (JSX) is a key feature that makes ReactJS fun and easy to work with. A developer can easily build a new user interface feature and watch it appear instantaneously. ReactJS incorporates HTML within JavaScript. ReactJS components make it unique. Developers do not have to struggle with the whole website application. Instead, they can leverage the ReactJS components to analyze complex user interfaces, user experience development, dividing it into understandable elements.

    ReactJS props help developers navigate custom data through a particular user interface component. This method is ideal in filling space during the rendering of JSX components. With the ReactJS State, developers can store changes in a single section. When utilizing ReactJS developers take all modifiable content in an application and keep it in one location or State. The State makes single website applications simple since all information comes from a centralized place.

    ReactJS leverages a virtual DOM, making apps fast. With the virtual DOM, the library can determine when to render or disregard, some DOM pieces. ReactJS can establish data changes when they occur. A highly responsive user interface is critical in improving the user experience.

    • React is Easy to Learn and User-Friendly

    ReactJS comes with numerous tutorials, documentation, and training resources which you can use to gain proficiency in the library. Developers with JavaScript experience can master React and start developing web applications using it within days. React is the view section in the model view controller model known as a popular JavaScript framework. While it is not entirely featured, it features an open-source JavaScript UI library, facilitating the easy execution of tasks.

    • It Allows Developers to Reuse Components

    A React application comes with components. Developers start creating small component-like menus, dropdowns, checkboxes, and buttons before building wrapper elements around the smaller components. Worth mentioning is that in React, every component comes with a unique logic. Developers can reuse any of the ReactJS components based on their preferences. Reusable code eases the development and maintenance of applications.

    ReactJS components are integrated with other elements to facilitate the development of complex applications from simple building elements. ReactJS leverages a virtual DOM-oriented method to load data in HTML DOM. the virtual DOM operates swiftly because it only modifies individual DOM components without loading the entire DOM each time.

    • It Offers an Exclusive Abstraction Layer

    ReactJS features a robust abstraction layer that blocks end-users from accessing the sophisticated internal components. Your developer will only need to understand some internal operations basics. React does not command any design patterns like Model–View–ViewModel (MVVM), Minimum Viable Product (MVP), and Model View Controller (MVC). A developer can develop an application’s structure the best way they know-how.

    • Boosts Performance

    The virtual DOM helps ReactJS boost performance. The DOM is a programming and multi-platform API that deals with XHTML, XML, and HTML. Many developers struggled with the DOM in the beginning. That slowed down the application performance. To solve this problem, ReactJS developers introduced virtual DOM built-in memory. It illustrates the website browser’s DOM.

    • ReactJS comes with a Collection of Developer Tools

    The ReactJS ecosystem features numerous customizable and ready-to-use graphics, charts, and documentation tools. With tools, developers can create a web application without refreshing the page.

    • Accelerates the Development Process

    Through ReactJS, developers can use separate parts of their app on the server and client-side, speeding up the development process. Different developers can write parts separately without affecting the application.

    • React is SEO-Friendly

    React is SEO-Friendly

    Traditional JavaScript frameworks are not SEO-friendly, and search engines struggle to read JavaScript applications. Following numerous developer complaints on this problem, ReactJS developers advanced the library, making it more search engine friendly.

ReactJS professionals can build huge web applications that modify data without refreshing the page. The core objective of React is to be simple, scalable, and fast.

  6. Why is Angular a framework?

    Because it provides a robust opinion on application designs. Further, it has out-of-the-box functionality, and developers do not have to determine the ideal routing libraries to utilize before starting the coding process. Still, angular offers less flexibility, limiting you to only use what the framework offers. Angular provides the following features.

    • Templates, based on an extended version of HTML
    • Routing, provided by @angular/router
    • Dependency injection
    • XSS protection
    • Ajax requests by @angular/HTTP
    • Utilities for unit-testing components.
    • Component CSS encapsulation
    • Angular/forms for building forms

    ReactJS offers developers the view in MVC and lets them determine the M and C. As a result, developers choose any libraries they deem fit. In this case, you get the liberty to utilize numerous fast-evolving and independent libraries. Even with this liberty, developers have to watch out for the corresponding migration and updates they make. Further, it’s worth mentioning that every React project is unique. Developers should determine its design and hierarchy, and this is where many things can go wrong.

    • React Offers the Following Out of the Box Features

    It comes with JavaScript Syntax Extension, an Extensible Markup Language developed atop JavaScript.

    • React has no dependency administration
    • Extensible Markup Language (XSS) protection
