Kotlin Coroutines And More
summary
Deep dive into Kotlin features with runnable examples on a public GitHub repo: coroutines (launch vs async, runBlocking vs coroutineScope, dispatchers IO/default/main, supervisor job), plus higher-order functions, lambdas with receivers and DSL builders, extension/infix/inline functions and type notes for Any/Unit/Nothing. Live demos fetch JSON from NASA open-notify JSON fetch and OpenWeatherMap; synchronous zip lookup shows ~279 ms while the async version drops to ~29 ms. Also shows sequences vs collections short-circuiting and scope functions like apply/let/also.
