    From http://docs.jsonata.org/higher-order-functions#filter Signature: $filter(array, function) Returns an array containing only the values in the array parameter that satisfy the function predicate (i.e. function returns Boolean true when passed the value). The function that is supplied as the second parameter must have the following signature: function(value [, index [, array]]) Each value in the input array is passed in as the first parameter in the supplied function. The index (position) of that value in the input array is passed in as the second parameter, if specified. The whole input array is passed in as the third parameter, if specified. Example The following expression returns all the products whose price is higher than average: $filter(Account.Order.Product, function($v, $i, $a) { $v.Price > $average($a.Price) })
