json.remove() Function
• Introduced in version 1.3b49
Removes a field from a JSON Object, or the value at the specified index from a JSON Array. If the field is not present in the JSON Object, it is returned unchanged. If the index does not exist in a JSON Array, a java.lang.IndexOutOfBoundsException is raised.

[h: jarr = json.remove(jobj, key)]Examples
[h:a=json.fromStrProp("a=1;b=44;c=12")] [r:json.remove(a, "c")]
[h:a=json.fromList("a,1,g,4")][r:json.remove(a,3)]Returns
{"a":1,"b":44}
["a",1,"g"]
