In plain words
Expo 2.0 is a development platform that lets developers build iOS and Android apps using JavaScript and React Native. It provides the Expo SDK with native APIs for both platforms, and includes tools for managing assets, handling push notifications, and building binaries ready for app store submission. The platform is designed for developers who want to create cross-platform mobile applications without writing separate native code for each platform.

Expo enables you to build cross-platform native apps using only JavaScript. In addition to React Native components, you'll have access to the Expo SDK, a library that provides a wide range of native APIs on iOS and Android. Expo can also manage assets for you, handle push notifications, and build your native binary for submission to the app store.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
