What Is React? – 2024 guide

React is a JavaScript library that is used to develop UI (user interfaces) and is responsible for how your web application will look. React is an open-source code created by Facebook Corporation, which is actively developing it together with the community. In particular, the library is used in React Native, a technology for creating native and hybrid applications for iOS and Android.

3 Reasons to Choose React for Your Web App

Let’s look at the pros of writing with React JS and why people use it.

Beautiful and comfortable

React, as a flexible declarative library, does not limit you in any way in the design of a web application. If you need to create a unique user interface, then React is the best choice. Developers (from https://keenethics.com/tech-elixir) will only need to describe how each part of the interface looks in different states, and the library will change them when receiving the right command.

Fast and productive

React makes the site not only beautiful but also productive. With it, the site acquires the ability to update only those parts of the page that need to be changed. The structure of the previous version is stored in the memory of the web application, which allows you to compare it with the new state of the interface.

Server-side rendering is just as important. In practice, the loading speed of the components of your web application will not depend on the power of the device on which the user opened it.

In addition, React is suitable for some non-standard tasks, in addition to converting HTML code into images in the browser. With its help, you can display dynamic graphics or make the application isomorphic – so that the server can render the pages for the initial load and the user sees the content instead of the “Loading” screen.

Good for a startup

React can be used in web applications of any scale, but it performs best in small, one-page applications with growth prospects. In particular, it is chosen for startups because of its easy payback. In addition, sites with React are highly rated by Google search bots. They like the user-friendly interface and the experience it provides.

Why Should You Choose React?

JavaScript XML is an extended syntax that is easier to work with and easier to find errors. For developers who know JavaScript and HTML, which are lightweight and popular languages, combining them in JSX makes the components easy to understand, and therefore no problems with refinement, testing, and support.

Functional programming

Code written with React is easy to test and reusable. Declarative views (one-way data binding) make it as predictable as possible compared to other frameworks and reduce errors during debugging.

At the same time, developers can create encapsulated components with their state and combine them into complex interfaces. JavaScript logic is not limited by templates – it allows you to easily transfer data between components from any part of the application.

The creators of React allow developers to use exactly as much of the library’s capabilities as they need and where they need it. React can be used on the server, for example with Node.js, but also for mobile application development with React Native.

In addition, you can simply add several dynamic widgets to the HTML page to make the interface more “live” and modern. If you want to use more React capabilities in the future, expanding its presence does not require much time and major changes to the page code.

Component Reusability in React

One of React’s standout features is its component-based architecture, a boon for developers seeking to streamline their work. Imagine creating a self-contained UI button with specific functionalities. Instead of recoding this button for different parts of your application, React allows you to reuse that component seamlessly.

This not only saves precious development time but also boosts code maintainability. Practical tip: When building components, think modular! This ensures that you have reusable pieces that can fit into different parts of your application puzzle.

Virtual DOM and Efficient Updates

React’s efficiency shines brightly with its implementation of the Virtual DOM. In traditional web development, any change, however minor, results in the entire Document Object Model (DOM) getting updated—a costly and often sluggish process. React ingeniously sidesteps this issue. Instead of updating the actual DOM directly, it updates the Virtual DOM—a lightweight copy.

This allows React to pinpoint precise changes and only update those parts in the actual DOM. For developers, this means swifter performance and a smoother user experience.

Thriving Community and Expansive Ecosystem

Diving into React doesn’t mean going it alone. There’s a buzzing community of developers continually enhancing the library. A quick search reveals a plethora of third-party libraries, tools, and extensions tailor-made to augment React’s already impressive capabilities. These resources, backed by a passionate community, ensure you’re always equipped with the latest tools and best practices.

State Management in React

Beyond components, managing data or “state” in React is crucial. While components might be the face of your application, state is its beating heart. React offers several tools for state management. Local component state is excellent for storing short-term data, while the context API helps pass data without “prop drilling”.

For larger applications, third-party libraries like Redux offer advanced state management solutions. Practical insight: Choose your state management tool based on the size and complexity of your application to maintain optimal performance.

Prioritizing Accessibility

React isn’t just about creating visually appealing apps; it emphasizes inclusivity. Ensuring your web applications are accessible is pivotal, and React provides tools and practices to craft UI components accessible to all, including those with disabilities. Following React’s accessibility guidelines doesn’t just make your application inclusive—it makes it more user-friendly for everyone, fostering a universal user experience.

React is the most popular Javascript library. Stack Overflow developer polls, Google search statistics, and GitHub all show a steady increase in demand for the technology itself and developers. Flexible, lightweight, and productive, React is used by Facebook and many other well-known companies from Netflix, where it adapts content for TVs with low performance, to Instagram, where it is responsible, even for geolocation.
