Coroutines and How They Work at a Low Level

▤ Summary

This article breaks down Kotlin coroutines and explains how they work under the hood. It focuses on Continuation, ContinuationImpl, and resumeWith to show how suspend functions are transformed into state machines. The text walks through generated bytecode-style output and illustrates how coroutine execution resumes after suspension points. It also compares coroutine internals with callback-style programming to help readers understand the execution model.
