AE's Script Editor logs only the last object in for loop

When I call the following in AE's Script Editor:

var arr = [ "a", "b", "c" ];
for(var i=0; i < arr.length; i++) {  arr[i];
}

Only the third (last) object is printed in the consol. Is this normal? I mean the whole script runs but only the last object is printed? I would really appreciate if somebody could explain me why don't

a
b
c

is printed.

Is it something that can be adjusted somewhere in the settings?
