Arrays in JS have no type the elements in them can contain any type and do not all have to match. Arrays are also passed by reference which means a reference to the object is passed in not the entire object. so my code creates a new array and then copies the passed in array first and then pops one element off the original array and the newary is returned array . This is put into newary build to accept a processing type of String, int, boolean, char, byte, and returnedfloat.
