Kotlin as Java++

on YouTube ↗05m

" summary

Claims that Kotlin is 100% Java-compatible and compiles to the same JVM bytecode while offering distinct features: a JavaScript and a native (LLVM) backend, and just-added first-class Android support from Google I/O. Shows nullable types opt-in to avoid the billion-dollar null error, zero-cost inline functions that avoid allocations at call sites, extension methods that compile to static helpers, and automatic delegation that generates boilerplate methods. Examples are literal bytecode-equivalent snippets and working Android/JS/native toolchains.
