Why Choose Only ReactJs for your Next Projects

ReactJs is the most popular front-end JavaScript library for building Web applications. Most fortune 500 companies use Reactjs In this article, we will learn what React.js is and why we should use Reactjs instead of other JavaScript frameworks like Angular.

What is React.js?

Reactjs is an open-source JavaScript library that is used for building user interfaces specifically for single-page applications. It’s used for handling the view layer for web and mobile apps. React also allows us to create reusable UI components. React was first created by Jordan Walke, a software engineer working for Facebook. React first deployed on Facebook’s newsfeed in 2011 and on Instagram in 2012.

React allows developers to create large web applications that can change data, without reloading the page. The main purpose of React is to be fast, scalable, and simple. It works only on user interfaces in the application. This corresponds to the view in the MVC template. It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.

Why Reactjs?

Now, the main question that arises in front of us is why one should use Reactjs. There are so many open-source platforms for making front-end web application development easier, like Angular, Vue. Let us take a quick look at the benefits of React over other competitive technologies or frameworks. With the front-end world-changing on a daily basis, it’s hard to devote time to learning a new framework – especially when that framework could ultimately become a dead end. So, if you're looking for the next best thing but you're feeling a little bit lost in the framework jungle.

It's Simplicity

Reactjs is just simpler to grasp right away. The component-based approach, well-defined lifecycle, and use of just plain JavaScript make React very simple to learn, build a professional web (and mobile applications), and support it. React uses a special syntax called JSX which allows you to mix HTML with JavaScript.

It’s easy to learn

React, compared to other popular frontend frameworks like Angular & Vue, is much easier to learn. In fact, it’s one of the main reasons why React gained so much traction in little time. It helps businesses quickly build their projects. You see, the harder it is to learn a particular technology or framework, the more time it will take to begin the development process. And we, as human beings, often tend to avoid things that are difficult to learn. But, since React is simple that is easy to learn and get started, businesses and big brands are more inclined towards using it.

It helps to build rich user interfaces

Today, the quality of the user interface in an application plays an important role. If the user interface is poorly designed, then it lowers the chances of an application to succeed. But, if an application has a high-quality User Interface, then there are better chances that your users will love to use the app.

Therefore, building rich user interfaces is sort of necessary for an application to survive and thrive. The good news is, React allows building such high-quality, rich user interfaces through its declarative components, which brings us to our next point.

It Increases Developers’ Productivity

Frequent updates often turn into headaches when an app has a complex logic and when a single modification in one component can dramatically affect other components. But, to combat this problem, Facebook has amplified React with the component reusability feature. Component reusability in React basically allows developers to redeploy the same digital objects.

The process is simple too! – developers, for example, can begin adding simple components such as buttons, text fields, and checkboxes 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 its own internal logic, which is easy to manipulate and as a result, boosts the productivity of application development.

Fortune 500 Companies adopt React

Still, doubt whether to use React or not? Thousands of companies, including some Fortune 500 companies, have chosen React JS for their Websites and React Native Mobile Apps.

Airbnb, Tesla, Shopify, Flipkart.com, UberEats, and Walmart are among the top brands that built their mobile apps using the React Native framework.

React web framework, on the other hand, is currently being utilized by famous companies including Netflix, Paypal, NASA, BBC, Lyft, and New York Times to name just a few.

React Native

Learning ReactJS comes with a bonus: React Native. React is not a ‘write once run anywhere library’, as the creators say, it’s a ‘learn once write anywhere’ library. Yes, you can write native apps for Android and iOS using React Native. Although you will not be able to use the exact same code you wrote for the web, you will be able to use the same methodology and the same architecture.

Performance & Virtual DOM

When you are about to develop a web application that involves high user interaction and view updates, you have to consider the possible performance issues. Although today’s javascript engines are fast enough to handle such complex applications, DOM manipulations are still not that fast. Updating DOM is usually the bottleneck when it comes to web performance. React is trying to solve this problem by using something called virtual DOM; a DOM kept in memory. Any view changes are first reflected virtual DOM, then an efficient diff algorithm compares the previous and current states of the virtual DOM and calculates the best way (minimum amount of updates needed) to apply these changes. Finally, those updates are applied to the DOM to ensure minimum read/write time. This is the main reason behind React’s high performance.
