The Basics of React JS Development

The React JS development framework makes it easy to build dynamic, modern, and powerful applications. You can use it to create user interfaces, reduce development time, and improve performance. In this article, I’ll outline the basics of this framework and provide some useful tips for improving your own apps.

Develop user interfaces

React is a powerful framework for building interactive, data-driven user interfaces. Its modularity allows for easy application state management and declarative UI design. This helps reduce memory usage and makes for faster application performance. The framework also supports component-based design and allows for reusable code.

React also provides excellent performance for large projects with a lot of data changes.

React is an all-in-one library that lets developers manage the frontend state of both web and mobile applications. is a powerful JavaScript library that helps developers develop interactive user interfaces more quickly. React is a popular JavaScript library, used by many big names in the industry.

Improve performance

When developing a React JS application, there are a few different ways to improve performance. First, you can use code splitting, which divides your app’s code into smaller chunks that are presented to the browser. This can be done via resource splitting or on-demand code splitting. Another way to improve performance is to minimize the number of events that trigger a call to your app. Mouse clicks, for example, will have a lower event trigger rate than mouse over or scrolling. This is important because the higher the rate, the more likely your application will crash.

Another way to improve performance when developing react js applications is to use performance profiling tools. These tools run in the Chrome browser and analyze the performance of your app. They can help you identify bottlenecks and eliminate unnecessary visualization. You can also use these tools to determine the exact time it takes to render components in your application.

Reduce development time

One of the easiest ways to reduce development time for ReactJS applications is to use supplementary libraries. These libraries are especially important when building MVPs. They help reduce the amount of code you have to write to make your apps look great. Moreover, these libraries also give you the tools to build components with ease.

Another way to reduce for ReactJS applications is to use virtual DOM. This technology lets you dissect a page into small components. This is useful when making small changes to a large page. It can also reduce the overall page load time.

Create pure components

When designing for the web, you can use React to create pure components. When a pure component renders, it will stop any re-rendering of its child components. This makes it the best option for applications that have no reliance on global state. A pure component will also avoid rendering any mutated props.

Pure components are the simplest components. They don’t depend on any variables outside their scope, making them ideal replacements for simple functional components. The best pure components are those that return only a render function. The biggest use case for pure components is providing performance optimizations. They are optimized by performing shallow comparisons on state changes. In addition, they automatically manage shouldComponentUpdate(), so they don’t need to re-render if the state changes.

Pure components also make developing components faster. Pure components will avoid rendering the previous API request and will call the render method only when the state of the component has changed. The Pure Component life-cycle method shouldComponentUpdate will automatically detect changes and call the render method when they are required.

Build mobile applications with React JS

In the last decade, mobile devices have become more common. We use smartphones and tablets to keep connected. According to the Pew Research Center, 85% of American adults will own a smartphone by 2021. Tablets are also becoming more popular, with the share of tablet owners in the U.S. increasing from 8% in 2011 to 53% by 2022.


React Native is an excellent choice for building a mobile application, but it is not the most suitable choice for complex applications requiring a large scale integration. The iOS and Android touch subsystems are too different to use the same unified API. Fortunately, the number of JavaScript frameworks and libraries is steadily growing. These new frameworks and libraries offer better performance, better usability, and fewer bugs.
