The Kotlin Compiler doesn’t convert your code to machine code directly, but it converts your code to bytecode instead. Then, the Kotlin Interpreter/Virtual Machine converts the bytecode to machine code during run-time/installation time.

If you see a method call that have space between, it is likely a Kotlin infix notation. — Whenever I read Kotlin code that has infix notation, it always confuses me. Maybe I should say I still haven’t gotten used to it? Honestly, it is just sugar syntax in my opinion. For example: val result = 2 plus 3 is the same as val result = 2.plus(3) 2…
