In any IT farm, the presence of React Js can be noticed. It is a popular open-source JavaScript library that has given a new meaning to front-end development. 

React, a JavaScript library is one of the most popular technologies for client-side development. Increasing demand for React is driving organizations and businesses to hire React developers. 

A great deal of need exists for React developers. A certain level of expertise, related skills, and the latest development techniques are required. Hence the quest – hire a react developer has become a challenge nowadays. 

History of React Js: 

Jordan Walke, a software engineer at Facebook, created React. It was released in 2011. First, ReactJs was deployed on the Facebook newsfeed since it is the largest social networking platform. 

Later on, it was picked up on Instagram in 2012.  In May 2013, Facebook made React an open-source library as it grew. 

The use of this technology by large companies began in 2014, with many being implemented. In 2015, React Native was also established as an open-source library. This allows the creation of native mobile apps for Android and IOS. 

In today’s world, many companies use React Js. It is constantly being updated and developed by Facebook.  

What’s So Cool About React Js?

Among developers, today, React is regarded as one of the leading libraries. With React, you can quickly create interactive UI elements with JavaScript. 

Some of the distinguishing features of this tool make it interesting and useful. Such as:  

• One-Way Data Flow

One of the major reasons React is so popular is because of its one-way data binding. React uses a mechanism that gives a unidirectional data flow. The developer cannot modify any component directly. 

But it can utilize the callback function in order to modify values. This unidirectional data flow helps developers gain better control over the web or mobile application. 

• Virtual DOM

Virtual DOM is one of the prime features of React JS. It creates an in-memory data structure cache. It can only re-render the actual components that were manipulated. 

The DOM will update the changes in the application, and there will be no memory wastage. This process makes app development quicker and cost-effective. 

• JSX Benefits

The JSX acronym stands for JavaScript XML. Developers used this for React components. JSX allows HTML quoting and uses HTML tag syntax to render subcomponents. 

It describes the appearance of an application’s UI. JSX is one of the best features that React Js has to offer. It makes the code easier to understand and debug.

• Easy to Update

The beauty of React Js is it is fairly easy and quick to use. Data changes over time, and the reconciliation process makes it easier to build apps. Because of re-renders, the developer does not need any specific data binding.

• Simple and Declarative

React is simply best for creating interactive user interfaces for web and mobile apps. It will express how apps should look at any given point in time.  While changing underlying data, React will automatically manage all user interfaces. 

A simple view is created for each state in your application. With the declarative feature, the code becomes more predictable and debuggable more easily.

• Building Encapsulated Components

By building encapsulated components, developers can manage their own state and compose them to make user interfaces. Component logic is written in JavaScript that allows passing rich data through apps. 

Because of React, a developer can reuse components. Since they are encapsulated, components help to support the code.

• Native Approach

React Native is a custom renderer for React Js. It is used for mobile applications. React Native uses native components instead of using web components. 

It permits the React code to make it compatible with Android and iOS platforms. Besides, it also provides access to the native features of these platforms. 

Flaws in React Js:

No technology is perfect. At the same time, React has been a great framework for web developers. It still has a few drawbacks. Despite the fact these may not turn you into a hater, these are worth noting. 

• Hard to Follow the Updates

React Js is updating itself continuously. Because of its frequent updates, developers find it hard to keep following the pace of development. 

It is difficult to maintain the codes as the framework updates too often. The growth is beneficial but it is also very tricky. 

• Not Ordinary Library

React Js is a large library. React has managed to gather numerous advantages for both the developers and clients. And it is not easy to maintain this powerful framework. It requires in-depth knowledge. 

• SEO Problems

Google and other search engines may not index or index dynamic web pages with client-side rendering. Although there are tools for debunking, there are a few confusions that haven’t been clarified yet. According to Google, its crawlers are capable of reading dynamic content. 

• JSX as a Barrier

JSX is a syntax extension for React JS. It has many advantages. But some developers find it a disadvantage. Developers complain about its learning curve and complexity. It requires in-depth knowledge, which isn’t always possible for developers. 

Interesting Facts about React Js:

The popularity of React as a front-end development tool has grown rapidly. It is a powerful tool that stands out. For this reason, developers flock to React. Anyways, craving some exciting facts about React? We got you covered. 

• Clean Abstraction: One of the admiral sides of React is that it provides good abstraction. It helps the user avoid being exposed to complicated internals. 

Using React, the user can avoid learning complicated internals. React does not impose any architecture or patterns like MVC/MVVM. It only focuses on the view layer.

• Flux and Redux: Flux complements React components by the unidirectional data flow. On the other hand, Redux is a kind of reinterpretation of flux architecture. It provides a single store which is not required in Flux. 

• SEO Friendly: One of the known features of React is using the benefits of search engine optimization (SEO). Because of rendering speed, developers can cut down page loading time and start ranking higher in search engines. 

Final Thoughts

For creating interactive applications for mobile and web, React is a great tool. Lots of developers are using it. However, an aspiring programmer should explore this technology. On top of it, there is a high demand for React Js developers these days. 

Several companies are searching for experienced and skilled React developers who can enhance their products. Besides, companies can benefit in various ways from hiring a professional React developer. The developers can prove themselves to be an incredible asset to the company.
