Programming Trends 2022: Why You Should Use ReactJS for Web Development

Being number one in application programming, a JavaScript library React is ideal for building your amazing apps. They may be real-time chat apps, e-commerce apps, video sharing apps, blogging and social media apps, and many more.

Let's figure out what it is, its React JavaScript examples, and the advantages you should consider before starting out your next app development project.

ReactJS for web development

What is React.js?

React is an open-source JavaScript library built by Facebook. It has the innovative view of a web development concept where you don't reload the HTML DOM (Document Object Model), which is a hierarchical representation of the web page content.

When your web page is loaded, a browser creates a DOM of this page.

With React, you don't have to reload the DOM every time. You load it once, including the elements that can be rendered and re-rendered whenever their state changes.

React has a range of advantages over other libraries:

  • Adaptability. React is very adaptive: you can develop new features in React without rewriting an existing code. Besides, you can render server-side using Node and power mobile apps using React Native.

  • Enhanced UI. You can create an excellent interactive UI with less effort than in the case of using native Javascript. You design views for each state, and React acts accordingly, updating the view along with the components where data changes.

  • Great developer experience. It is simple to learn and is component-based. React allows building encapsulated components that manage their own states and compose them to create complex UI.

  • Meta's support. This library is used heavily in Facebook and Instagram apps. Their developers use over 50,000 React components for producing apps and massively contribute to GitHub in their production environment.

  • Easy testing. UI browser testing on React is way easier than with other libraries. It requires little to no configuration, and a large number of test suites can be run at a time.

Comparing React With Other JS Libraries and Frameworks

A shortest React example looks like this:

It displays a heading saying "Hello" on a page.

One of the Solvd software engineers, Mykhailo Melnyk, who's been working with React since 2015, explained that his choice of becoming a React developer was based on two factors.

"The community is super cool. Besides, React is a javascript library, not a framework (like Angular), and you can choose your stack."

Angular is also open source, created by Google, but it is a full-blown framework. AngularJS lets you extend HTML vocabulary for your application and is widely used for large applications like video streaming apps or music streaming apps.

The Vue library didn't exist back then. On the other hand, Angular was in its early versions, and it never actually got to React's level. React is a key programmer's choice because it gives more freedom and better management of both components and application.

React functions well for Single Page Applications (SPAs) that are web applications and don't use the default method of loading new pages entirely. Instead, they take new data from the backend by interacting with a web browser and refreshing a current web page.

Supplementary Libraries to Use With React

You can harness your React development and support it with supplementary libraries, like Material UI or Ant Designs. Using a robust library for creating your UI design will allow you to reduce application development time. That is vital, especially when it comes to MVP building, where time is of the essence.

A downside that engineers may experience is that working with a UI library, although they are extremely customizable, sometimes pose difficulties, such as getting a date-picker component to look the way a UX/UI team or a client have envisioned it, and building up many custom components, thus defeating the purpose of using a library.

React Javascript is an indisputably great language for programming web pages and applications, and within that JS spectrum, it is still unchallenged. There are other players in the arena, but professional web app developers would confirm that React still remains on top of others in 2022.
