How to clean an array in Haxe correctly?

Question

What is the most efficient way to clear an array in Haxe? Currently, I'm just assigning a variable to an empty array.

I found this on the internet:

public static function clear(arr:Array<Dynamic>) {
    #if cpp
    arr.splice(0, arr.length);
    #else
    untyped arr.length = 0;
    #end
}

Is this the best way? I am concerned about two goals, JS and CPP.

For the most part, you can simply use reassignment for an empty array to clear the array; this becomes problematic if array reference is important. In this case, it works well for you.
