    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"
