Explore the world of asynchronous programming in this 33-minute conference talk from WeAreDevelopers Conference 2017. Dive into Rxjs as a superior alternative to callbacks and promises for handling async operations. Learn how Rxjs elegantly combines various async elements like ajax, callbacks, and events. Discover the concept of observables, understand subscription and unsubscription, and explore powerful operators like flatMap. Examine practical applications including AJAX handling, caching, and streaming. Compare Rxjs with traditional promises, addressing error handling and dependencies. Gain insights into testing strategies, including marble testing for reactive programming. By the end of this talk, acquire a comprehensive understanding of Rxjs and its potential to revolutionize your approach to asynchronous programming.
