Pros and Cons of React Js

The influential JavaScript library React is used to create user interfaces. Jordan Walke, a Facebook software engineer, created it in 2011 with the aim of combining the speed of JavaScript with modern rendering methods to create websites that are highly interactive and sensitive to user feedback. Since 2013, React JS has been an open-source project, and it is now used by some of the world’s most well-known businesses, including Yahoo, Dropbox and Netflix.

Since business owners increasingly want to create websites that alter data when reloading pages, the demand for React JS developers is rapidly increasing. However, not everybody who wants to try out this JavaScript library is aware of the most significant benefits and drawbacks. It’s difficult to know whether React JS is the right technology for the job without first understanding its strengths and limitations.

Advantages of React JS

  1. Easy to Use:

It’s a lot easier to understand and use ReactJS. It includes a lot of notes, tutorials, and training materials. Any developer with a JavaScript background will quickly learn React and start building web apps in a matter of days. It’s the V(view part) of the MVC (Platform-View-Controller) model, and it’s also known as a JavaScript system. It isn’t completely featured, but it benefits from the open-source JavaScript User Interface(UI) library, which aids in task execution.

  1. Component reuse

Why would you waste time and money constantly reinventing the wheel when you can easily reuse code that has already been developed and tested by other developers? React JS makes use of components, which allow you to break down the user interface into separate, interchangeable parts and think about each one separately.

Chartify, a light-weight and customizable chart-component, Halogen, a set of highly custom made loading-spinner animations, and Material UI, a collection of components that implement Google’s Material Design, are just a few of the free components listed on the official React JS website.

  1. Virtual Dom

Since it’s necessary to recalculate the CSS, reconstruct the layout, and basically repaint the entire web page any time the DOM changes, the Document Object Model (DOM), a program interface that represents an XML-document as a tree-structure where each node is an object representing a part of the document, is inefficient and sluggish.

The so-called Virtual DOM is used by React JS to solve the DOM’s inefficiencies. The Virtual DOM, like the real DOM, uses a node tree to represent all elements and their attributes. React JS updates the Virtual DOM and determines if it varies from the actual DOM when anything changes, upgrading the existing DOM only with what has actually changed.

  1. A Strong Community

Due to the fact that React JS is an open-source library, it has a large and flourishing community of users and developers. The project has over 130,000 stars on GitHub and has been forked over 20,000 times. Independent developers from all over the world are actively suggesting new functionality and fixing tiny and big bugs.

Since React JS has always been a Facebook project, it benefits from the support and resources of one of the world’s most profitable tech companies, so there’s no reason to think it’ll go away anytime soon. In reality, React JS’s popularity has been steadily rising over the years, which is fantastic news for anyone who uses it.

Disadvantages of React JS:

  1. Constantly changing with updates:

The rapid speed of growth has both benefits and drawbacks. In the event of a disadvantage, since the world is constantly changing, some developers are hesitant to relearn new ways of doing things on a regular basis. With all of the constant updates, it may be difficult for them to adopt all of these changes. They have to keep their skills up-to-date and learn new ways of doing things on a regular basis. Which just does not seem that feasible.

  1. Poor Documentation

This is a consequence of the rapidly changing updates, which is typical as technology is continuously changing and can lead to development issues. For certain JavaScript developers, integrating new features might just be a burden. The development of documentation and guidelines for this new functionality is another circle of hell. Some JavaScript programmers write their own directions for specific tools used in projects to make the situation less harmless.

  1. JSX is a Barrier

JSX is used by ReactJS. It’s a syntax extension that lets you combine HTML and JavaScript. Although this method has its advantages, some members of the development community regard JSX as a barrier, especially for less experience developers. Developers stress about the learning curve difficulty.

  1. SEO Issues

There’s been growing concern that Search engines like google will be unable to index, or will index poorly, dynamic web pages rendered on the client side. These concerns haven’t been proven beyond a reasonable doubt, and there are debunking materials available. In 2014, Google confirmed that its crawlers are able to read dynamic content. As a result, we cannot guarantee that your ReactJS app will not be indexed by Google.

However, you should conduct additional testing to ensure that your app creates a Google buddy, as some users have reported issues. To learn more about how crawlers interact with your React apps, SEO experts recommend running them through one of the Google Search Console tools.
