Reactjs is an open-source JavaScript library widely known for creating dynamic and highly responsive user interfaces. With a component-based architecture, Reactjs emerges as a very efficient solution for developing a fast & scalable front-end for web and mobile applications.

It primarily focuses on building natural, interactive and appealing applications. Reactjs demands a minimal coding effort on the part of developers and offers the best rendering performance.

However, Reactjs is a lightweight view library that only supports the UI components. Therefore, it requires integration with other technologies and tools (such as Flux and Redux) in order to get a full-fledged architecture.

With remarkable features that include real-time updates, server-side rendering, and so on, this JavaScript library has gained immense popularity among the developer's community.

Growth and Popularity of Reactjs –

Reactjs was created by Jordan Walke, a software engineer at Facebook, in the year 2011. His objective was to develop a JavaScript-based library to streamline the app development process and facilitate a more comfortable user experience.

More and more businesses are recognizing the importance of a good UX and Reactjs serves as the easiest way to streamline your app’s user experience.

In 2011, Facebook applied this new library to its web-based application and in 2012 it was applied on Instagram. The library went open source in 2013 and soon its implementation expanded.

More and more developers started employing Reactjs for developing single-page and large scale applications. Twitter, Netflix and Dropbox are just a few names from a massive list of tech giants who have used Reactjs for their web apps.

In 2015, Facebook launched Reactjs as a cross-platform mobile app development framework. Soon after its release, the framework got widely accepted by the companies that specialize in the mobile-first strategy.

Why Choose Reactjs For Your Next Project: Features of Reactjs

The developer community loves Reactjs for its robust features. Some of the Reactjs features that distinguish it from the rest are:

1. Virtual DOM

Virtual DOM is one of the chief characteristics that facilitate fast and flexible application development using Reactjs.

Its memory reconciliation algorithm enables React to replicate a web page in its virtual memory. In this way, a virtual DOM is the representation of an original DOM.

With every modification in the web application, the virtual DOM re-renders the entire user interface. In a virtual DOM representation, only the components that have actually changed are updated and not all the components.

Thus, Reactjs makes the app development process quicker and cost-effective.

2. JSX

JSX stands for JavaScript XML. It is a markup syntax that is very similar to HTML and is used to describe the appearance of an application’s UI.

JSX is one of the best features that Reactjs has to offer. It makes the syntax, used by developers to create React components, almost identical to the HTML they will inject in the web page. This makes writing the building blocks of Reactjs effortless and simple for the developers and gives them an easy way out.

3. One-way data binding

One of the major reasons why you should choose Reactjs for your next project is its one-way data flow. Reactjs uses a unidirectional data flow. Meaning, the developers cannot edit any component directly. They have to utilize the callback function in order to make changes in the components. This process is called one-way data binding.

Reactjs uses Flux, a JavaScript app architecture, to control the data flow from a single point. A unidirectional data flow helps Reactjs developers to gain better control over the web or mobile application. This enhances the flexibility of the application and makes it more efficient.

4. Declarative UI

As mentioned earlier, Reactjs is the best for creating engaging and interactive user interfaces for mobile and web applications.

In an event of data modification, Reactjs adequately renders and updates just the right components. It generates a simple view for each state of the application. This feature makes the code more readable and simpler to debug.

5. Component-based architecture

The architecture of Reactjs is component-based. In other words, the UI of a React-based mobile or web application is divided into multiple components. Each component has its own specific logic. The logic is written in JavaScript instead of using templates. This enables Reactjs developers to pass the data throughout the application without affecting the DOM.
