React Native is an open-source framework developed by Meta (back then still called Facebook) that enables developers to build mobile apps using JavaScript and React. It's different from other mobile app development frameworks thanks to the way it allows for the creation of truly native apps by using native components instead of mere web views. This approach offers several advantages over traditional mobile app development methodologies, making it a popular choice for companies looking to build one-of-a-kind applications. In fact, some of your favorite platforms were built using this technology, like Facebook, Uber, and Pinterest
