Functions

Functions are a way to define a “subroutine” that can be executed repeatedly. Every function has it’s own scope of variables independent of it’s caller.

define myfunc() {
    println("I did some things!");
}

special functions

The main function is treated in a special way by the compiler. This function is the entry point for your program. There may only be ONE main function per program. Having zero main functions or more than one will result in a compile-time error.

returns and return types

Functions can return a value of a specified type. This return value can be captured by the caller.

define myfunc() -> i32{
    return 9;
}

define main() {
    println(myfunc()); // println uses the returned value from calling myfunc()
}

arguments

define add(x: i32, y: i32) -> i32 {
    return x + y;
}
