Difference Between React and React Native

Posted on

In this article, we will compare React JS and React Native, the two popular JavaScript-based tools. We will see why both are important and how they are different from each other.

Anyone familiar with front-end development knows that there are many frameworks and libraries to choose from. However, most of them only make life easier for the developer to a certain extent. On the other hand, there are a few libraries that allow developers to create highly interactive user interfaces on the web as well as the mobile platform.

The most important of them are React JS and React Native. So, let’s compare React JS vs React Native to understand which one should be used for which type of project:

What is React?

React is a JavaScript library for creating user interfaces. It is maintained by Facebook and a community of individual and corporate developers to take advantage of the advantages offered by ReactJS.

React can be used as a base in the development of single-page or mobile applications. However, React is only about rendering data in the DOM, and so building React applications usually requires the use of additional libraries for state management and routing. Redux and React Router are respective examples of such libraries.

The advantages of ReactJS

  • One-way data binding: In React JS, we need to follow one-way data flow or one-way data binding. In simple terms, this means that data only flows in one direction.
  • Reusable Components: Components are the building blocks of React JS that are combined to create an application and these components are reusable.
  • Virtual DOM: This concept makes React JS unique. Virtual DOM is a programming concept in which an ideal or “virtual” representation of a user interface is kept in memory and synchronized with the “real” DOM ​​by a library such as ReactDOM. This process is called reconciliation.

Limits of React JS

  • React JS is a limited framework that only works on the front-end. It is useful for developing responsive, dynamic and fast web applications. Its sole purpose is to generate a view of what the user sees on their device.
  • You cannot modify the DOM directly in React; you need to create a component.
  • You can’t use two-way data binding like Angular does.
  • React has no opinion on how your styles should be organized or loaded into the application.

What is React Native?

react native is a framework for building cross-platform applications. It uses the same design as React, allowing you to compose a rich mobile UI from declarative components.

With React Native, you don’t create a “mobile web app”, an “HTML5 app” or a “hybrid app”. You are creating a real mobile application that is indistinguishable from an application created using Objective-C or Java. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put these building blocks together using JavaScript and React.

The benefits of React Native

  • One of the many benefits of React Native is that it lets you write iOS and Android apps with a single JavaScript code base. It also lets you develop for multiple platforms at the same time, which is handy for developers who are already familiar with ReactJS.
  • Code reusability: JavaScript is one of the most popular programming languages, and mobile developers are already familiar with it. This means they won’t have to learn new concepts to understand what’s going on in a React Native project.
  • Performance: it is possible to integrate code written in Swift, Java and Objective-C with applications written in React Native. This allows developers to use the best features of each language to create a highly effective product.
  • Easier UI development: One of the biggest advantages of React Native is that it uses native components instead of web components as building blocks. This provides greater flexibility and faster performance than a hybrid application approach or developing multiple separate applications for android and iOS.
  • An active community: Since its release three years ago, React Native has become very popular among mobile app developers. Therefore, there are now many third-party libraries that can be easily integrated into your code if you are looking for a practical solution to a specific problem.
  • Improved cost-efficiency: Cross-platform apps are more economical to develop than native apps because they can be launched on two platforms at once.

Limitations of React Native

  • React Native is still not the optimal solution for building a mobile application. It suffers from performance issues compared to native solutions and does not provide enough custom modules to cover all a developer’s needs.
  • React Native also has limitations in providing a pixel-perfect UI. On the other hand, it is much easier to create a pixel-perfect user interface in Android than in iOS. For example, it is much more difficult to achieve perfect placement of UI elements with React Native than with Xamarin. Forms, which has better built-in support for layout options.
  • Also, React Native doesn’t give you all the features available in the latest versions of iOS and Android, unless they’ve been baked into the core of React Native, or unless you create them yourself. -same.

Which is better: react or react native?

If your business is starting to revolve around software development, to stay competitive you will need to look into React JS vs React Native. Both will be useful, depending on the type of applications you are going to create.

If you need a well-developed application, which will take full advantage of the technical capabilities of the platform it will be deployed on, you should use React Native. If instead you need a cross-platform application that will reinterpret the elements and adapt them to each different platform, creating it using React JS would be more suitable.
