Introduction to Coroutines

on YouTube ↗46m

" summary

Shows that Kotlin adds coroutines as first-class primitives using the suspend modifier and coroutine builders like launch and async; demonstrates 100,000 coroutines printing dots successfully while the equivalent thread version throws OutOfMemoryError. Explains sequential-by-default design (use explicit builders for concurrency), the Deferred future type and await extension for Java interop, sequence builders with yield, and that coroutines are lightweight, library-driven, and currently experimental but production-ready.
