The confusion between React and React Native primarily stems from their names and shared origin. Facebook introduced both; both employ component-based architecture, and both use JavaScript. Those unfamiliar with their difference often end up comparing React vs. react native, like react native vs. Flutter, to choose the right tech stack for their project. Their name gives the impression that they are the same or at least very similar.
React JS:
React, originally termed “React.js,” is an open-source JavaScript library for building user interfaces. It was developed by Jordan Walke, a software engineer at Facebook, and was first introduced in 2011 at Facebook’s newsfeed feature.
React gained rapid popularity due to its unique approach of breaking UIs into reusable components and its virtual DOM implementation, which optimized rendering performance. The idea was to create fast, scalable, and simple user interfaces. React was then open-sourced at JSConf US in May 2013.
React Native:
Inspired by React’s architecture and potential, Facebook introduced React Native in 2015 during their F8 conference. React Native leverages the same design as React, letting developers use a similar component-based structure and React native IDEs to create native applications for both iOS and Android.
Instead of targeting the browser, React Native targets mobile platforms, allowing JavaScript to be executed on the device and interact with native APIs. React Native allows developers to write native apps using a familiar web development paradigm.
