Number.pad(size, ch)
String.pad(size, ch)
pads AND truncates Number or String to specified size. If no argument is specified or size is zero,
return String without padding or truncating.
ARGUMENTS:
size (Number) specifies padding size -- >0 for right padding <0 for left padding
(String), specifies character(s) used for padding -- size is length of size String.
right padding if numeric e.g. "0..." -- otherwise left padding
ch (optional) specifies padding character(s) when size is Number.
default is blank character for String or Number when size is > 0
default is "0" for Number when size < 0
EXAMPLES:
'1'.pad('00') returns: "01"
1.pad('00')
'1'.pad(-2)
1.pad(-2)
1.pad(2) returns: " 1"
1.pad('...') "..1"

i.e. must return true to keep looping
otherwise returns true after every item processed
some(): quits loop and returns true when callback function returns true;
otherwise returns false if all items return false
i.e. acts like includes() -- quits on 1st success
ARGUMENTS:
callback function called for each defined array element
thisObject Object used as this when executing callback function
RETURNS:
nothing
TODO:
filter (creates a new array including elements where the filter function returns true

reduce (builds up a value by repeated calling the iterator, passing in previous values;
