kotlin-stdlib · the supported surface

The standard library,
runnable in the page.

minikotlin ships its own hand-written stdlib — no JVM runtime underneath, just the language core compiled to WASM. Below is the surface it actually supports — ~190 APIs across 15 areas, every chip and snippet verified to compile and run on the compiler itself. Edit any example and hit ⌘↵ to compile to WebAssembly and run it, entirely in your tab.
