From http://docs.jsonata.org/string-functions.html:
$join(array[, separator])
Joins an array of component strings into a single concatenated string with
each component string separated by the optional separator parameter.
It is an error if the input array contains an item which isn’t a string.
If separator is not specified, then it is assumed to be the empty string,
i.e. no separator between the component strings. It is an error if separator
is not a string.
Examples
$join(['a','b','c'])=="abc" $split("too much, punctuation. hard; to read",
/[ ,.;]+/, 3) ~> $join(', ')=="too, much, punctuation"
