" summary

Demos show concrete Kotlin tools and results: timing with measureTimeMillis proves Java parallel streams drop 800ms to ~100ms on multiple cores; collection APIs like chunked/windowed compute 10‑year and sliding 5‑year ocean temperature averages from CSV; scope functions apply, let, also initialize servers (Ktor), handle nullable string capitalization, and insert logging; URL.readText plus Gson/Ktor deserializes JSON into data classes; lazy/observable/vetoable delegates and a smartphone delegate example; native‑image builds a native executable and cuts startup time significantly.
