Coroutines and Concurrency

Explore how Kotlin coroutines work as cooperating functions that enable concurrency by switching execution between tasks without blocking. Understand the difference between parallel and concurrent execution to improve asynchronous programming in Kotlin.

Most people put on the underwear before putting on the pants, though the order may be in reverse—even then, superwoman and superman don’t put them on at the same time.
