 looking up the last character of a string (version: 0)

tests with a short string and a long string, to help discern which methods are tied to the string length, and which are not.

Comparing performance of: short endsWith vs short regexp vs short charAt vs short brackets vs short CharCodeAt vs short slice vs short substr vs short substring vs long endsWidth vs long regexp vs long charAt vs long brackets vs long charCodeAt vs long slice vs long substr vs long substring
