# # `join()`

The join method joins the collection's values with a string:

    collect(["a", "b", "c"]).join(", ");
    //=> 'a, b, c'

    collect(["a", "b", "c"]).join(", ", ", and ");
    //=> 'a, b, and c'

    collect(["a", "b"]).join(", ", " and ");
    //=> 'a and b'

    collect(["a"]).join(", ", " and ");
    //=> 'a'

    collect([]).join(", ", " and ");
    //=> ''
