Exploring Coroutines in Kotlin

on YouTube ↗44m

" summary

Kotlin coroutines let code stay sequential while becoming nonblocking: the demo turns blocking URL reads for a localhost stock-price service (port 8085) into concurrent work with launch/async/await, cutting three ~1s serial calls to about one second total. Compiler-desugaring shows a continuation added as second parameter for every suspend function. Examples include sequence/yield continuations and a working stock-price+IP demo; the async version executes correctly and measures the speedup.
