Introduction to ReactJS
What is ReactJS?
React JS is a JavaScript library used in web development to build interactive elements on websites. But if you’re not familiar with JavaScript or JavaScript libraries, that’s not a helpful definition. It is used exclusively for “client side” programming (helps in building things that a user will see on screen in their browser window), which makes React JS a frontend library.

But if you’re not familiar with JavaScript or JavaScript libraries, that’s not a helpful definition. It is used exclusively for “client side” programming (helps in building things that a user will see on screen in their browser window), which makes React JS a frontend library.
So let’s take a step back and deal with those terms (Java Script/libraries)first.
JavaScript libraries are collections of pre-written JavaScript code that can be used for common JS tasks, allowing you to bypass the time intensive (and unnecessary) process of coding by hand.
OK, so let’s get back to React.React is a JavaScript library that specializes in helping developers build user interfaces, or UIs. In terms of websites and web applications, UIs are the collection of on-screen menus, search bars, buttons, and anything else someone interacts with to USE a website or app.
Use of ReactJS
React doesn’t enforce strict rules for code conventions or file organization. With React, you can use as much or as little as you need due to its flexibility.
Easier Creation of Dynamic web applications
ReactJS is one of the most popular libraries practiced to generate complex Frontend applications. It is essential to say that web components built for a mobile application have all the benefits that the React library provides, such as dynamic page and style loading. A rich ecosystem and a component-based approach allow you to reuse already written code many times; without resorting to significant time costs.
It is considered best among developers to use ReactJS for most web applications. The fact is that the tool is potent and can execute scripts of almost any complexity. It is ideal for dynamic sites where constant updating is essential
Increased productivity
Component reusability in React basically allows developers to redeploy the same digital objects.
The process is too simple– developers, for example, can begin adding simple components such as button, text fields, and checkbox and then move them to wrapper components, which are ultimately moved forward to the root component.
This approach basically provides better code maintenance and growth as each component in React has their own internal logic, which is easy to manipulate and as a result, boosts the productivity of application development.
Ensures to have a stable code
React follows downward data flow to ensure that the parent structure don’t get affected by any modifications in its child structure. So, whenever a developer makes changes in an object, he or she only needs to modify its states and make proper amendments. This way only a specific component will be updated.
This data flow and structure, as a result, provide better code stability and smooth performance of the application.
SEO friendly features
For any online business, search engine optimization is the gateway to success.
The lower the page load time and the faster the rendering speed, the higher an app will rank on Google.
Thanks to the fast rendering, React, compared to other frameworks, significantly reduces the page load time, which greatly helps businesses in securing the first rank on Google Search Engine Result Page.
Considering all the uses of React JS we have seen it can be said that ReactJS is non-risky, responsive and advanced. It can build high-end applications easily and all data changes can be applied repeatedly. It helps developers with virtual DOM which is much faster and user-friendly.
Why ReactJS is Popular?
Let’s see the key benefits of React JS to understand why it stands out from other front-end development frameworks.
Performance:
React JS is designed in a way to provide high performance in mind. The core of the framework offers a virtual DOM program and server-side rendering, which makes complex apps run extremely fast.
Usability:
Deploying React is fairly easy to accomplish if you have some basic knowledge of JavaScript.
In fact, an expert JavaScript developer can easily learn all ins and outs of the React framework in a matter of a day or two.
Flexibility:
Compared to other frontend frameworks, the React code is easier to maintain and is flexible due to its modular structure. This flexibility, in turn, saves huge amount of time and cost to businesses.
Speed:
The React basically allows developers to utilize individual parts of their application on both client-side and the server-side, which ultimately boosts the speed in the process of development
Reusable components:
One of the main benefits of using React JS is its potential to reuse components. It saves time for developers as they don’t have to write various codes for the same features. Furthermore, if any changes are made in any particular part, it will not affect other parts of the application.
Thousands of web applications use it today, from well-established companies to new start-ups. A few notable mentions are:
- Netflix
- Uber
- Airbnb
- The New York Times
- SoundCloud
- WhatsApp Web
React has also grown more robust and can now be used to build native mobile applications using React Native and Desktop apps using Electron.js.
Benefits of using ReactJS
Using React, you can create a single button, a few pieces of an interface, or your entire app’s user interface. You can gradually adopt and integrate it into an already existing application with a sprinkle of interactivity or, better yet, use it to build full-fledged powerful React applications from the ground up, depending on your need.
React framework is the perfect choice when you want to develop Single Page Applications (SPAs) as it can rewrite and update content on a web page without requiring to reload or refresh the page.
