kotlinc is the compiler. So you're going to compile Kotlin sourcecode to be run on a JVM. (There's Kotlin native, JS and so on but without script option)

The script option still compile it, I think. Last time I checked, I used kscript to write Kotlin script and there is some overhead when running a script (compilation), however it kscript can also cache the compiled code.
