 * call will use a Base 36 string (10 numbers + 26 letters) based on an incremented number. The
 * incremented number always starts at 0 and can be reset for testing purposes using
 * [resetUniqueIdCount](#resetuniqueidcount). [setUniqueSeed](#setuniqueseed) can also be used for
 * testing or server side rendering to get the same results during hydration.
