humanJoin.js (@maynoothuniversity/human-join)

A function for converting JavaScript arrays into human-friendly lists, e.g. ['apples', 'orangess', 'bananas', 'pears'] to 'apples, oranges, bananas & pears'.

Both the separator and the conjunction are configurable, and there are built-in shortcuts for common needs like the so-called Oxford Comma. The function also supports wrapping each of the items in the list with a string before they are joined. If wrapping is requested, it will be default be inteligently mirrored, so wrapping with << will result in output of the form: <<apples>>, <<oranges>>, <<bananas>> & <<pears>>.

Synopsis:

var human = humanJoin(list, [options]);

The list can be an array or the special arguments variable.

The options are, as their name suggests, optional, and can either be a single string as a short-cut to a boolean option, or, an associative array specifying multiple options.
