RxJS provides both the observable primitives as well as a broad set of operators for the creation and transformation of data. And, as you know, Angular leverages RxJS for cancelable asynchronous actions and events. In our opinion, the two are a perfect match. Interactions with web applications are asynchronous in nature and Angular provides a robust solution to detecting those asynchronous actions, enabling developers to build interactive experiences for the web with ease.

In this series on RxJS operators, we help you learn the operators. As you likely know, there are a lot of them, and it can be difficult to know what each of them does, and often, how to determine which operator, or operators, are succinct and current for solving the complexities of streaming data, actions, and events in our applications.

Join panelists Jennifer Wadella, Aaron Frost, Brian Love, and guest Jan-Niklas Wortmann as we explore the creation operators. These functions enable the creation of new observables, or the composing of existing observables into a new observable stream. Jan-Niklas is a Google Developer Expert in Angular and volunteers his time on the RxJS core team. Listen in and learn from Jan-Niklas as he teaches us about many of the creation operators in RxJS. We're sure you'll walk away from this episode with a new and expanded knowledge of RxJS.
