React and React JS are the same thing: one JavaScript library, officially named React, created at Facebook (now Meta) in 2013. React.js and ReactJS are informal spellings that stuck around from its early years. The only genuinely different technology is React Native, which targets mobile apps.
In this blog, I will clear up any misunderstandings and explain why you may see these different names. By the end, you will know the difference between React and React JS, why some developers say "React," why others say "ReactJS," and which one is more commonly used in the frontend industry. Let's get started!
React vs React JS: Breaking Down the Confusion
When you compare React vs React JS, you might wonder if they are two different technologies or have different features. The truth is that the difference between React and React JS is just in the naming.
React is the official name used in documentation and by the developer community. React JS is a less formal term that highlights React's connection to JavaScript.
The root of the React vs ReactJS comparison goes back to the early days of React's release. When Facebook introduced the library in 2013, different sources used variations like React, React.js, and React JS.
Nowadays, React is the standard name, but you may still see other forms in blogs, tutorials, and community discussions.
In practice, when you hear ReactJS vs React, remember they are the same thing. My advice is to focus on learning how to work with React, not which name to use.
📝Note: Often, when people ask what is the difference between React and ReactJS, they actually mean React vs React Native comparison. Such confusion is more common among non-tech people. Or newbies.
React or ReactJS: Both Are Correct
React vs React.JS is like sneakers and trainers. Depending on where you are, people can call them different names, but at the end of the day, they both refer to the same type of shoes.
Similarly, React or ReactJS are two names for the same JavaScript library, used interchangeably without any difference in meaning.
Whether you choose to call it React or React.JS, you will be right, and any professional developer will understand you because we know there is no functional difference between React and ReactJS.
React is used to develop big and small web projects. It differs from other tools because of its freedom of action. That is why React is used for applications and services in e-commerce, social networks, messengers, and entertainment. The technology is also used for task scheduling and any other interaction projects.
As of 2026, React is on version 19 and is still actively maintained by Meta. It is also the foundation for full-stack frameworks like Next.js - if you are choosing between plain React and a framework built on top of it, see our Next.js vs React comparison.
Final Word
Are React and React JS the same technologies? Absolutely! But you are not the same anymore. Now that you know the difference between React and React JS, you can be proud of yourself because you have become a better web developer than before 😄

Yes. React, React.js, and ReactJS all refer to the same JavaScript library for building user interfaces. The official name used in the documentation is simply React.
React (React JS) builds web interfaces that run in the browser; React Native uses the same component model to build native iOS and Android apps. They share concepts and much of the syntax, but they are separate technologies for different platforms.
The variants date back to React's 2013 launch, when blogs and tutorials used React, React.js, and ReactJS interchangeably to signal it was a JavaScript library. The community and official docs settled on React, but the older spellings still circulate.
Yes, I recommend getting a solid understanding of JavaScript before diving into React. React is a JavaScript library, and many of its features build on core JavaScript concepts. Good knowledge of JavaScript will make learning and using React much easier.
React is versatile and can be used to build various applications, including Single-page applications (SPAs), Dynamic web applications, E-commerce platforms, Social media apps, Messaging apps, Dashboards, and admin panels.
