Some developers may be confused between “React.js” and “React” because of the interchangeable use of the terms and the lack of clear distinction between the two. Additionally, some people may use “React.js” to refer specifically to the core React library, while others may use “React” to refer more broadly to the entire React ecosystem, which includes other tools and libraries such as React Native and Redux. So what is the difference between these two?
Another possible source of confusion is that the term “React.js” may sound like a file extension or programming language, which could lead to misunderstanding about its actual purpose and capabilities.
React.js is based on the concept of a virtual DOM (Document Object Model), which is a lightweight representation of the actual DOM that allows for faster updates and rendering of the user interface. It also uses a unidirectional data flow, which makes it easier to manage complex user interfaces and data structures.
