Fresh Async With Kotlin

Explore asynchronous programming approaches and their evolution in this conference talk from GOTO Copenhagen 2018. Delve into Kotlin Coroutines, a fresh approach to async programming, and compare it with traditional async/await methods based on futures/promises. Learn about suspending functions, dispatchers, and structured concurrency in Kotlin. Discover how to implement asynchronous operations using Retrofit, handle callbacks, and analyze responses. Examine use cases for async functions and understand why Kotlin doesn't have an await keyword. Gain insights into idiomatic Kotlin async programming and see practical examples, including a concurrent Fibonacci sequence implementation.
