RxJS started as a simple idea: treat events as first class citizens and make asynchronous programming composable. That dream grew into a library that influenced countless projects across the industry. In this talk we will explore why RxJS was created, how it evolved from its early days into a core tool for reactive programming, and what it has become today. We will look at the many domains where RxJS has spread, from backend systems to frontend frameworks, and discuss how its core concepts shaped modern development. Finally, we will explore where RxJS is headed, including its role in the browser and how you can take advantage of native Observables today to write cleaner, more expressive code.
