String

XML nodes are serialized to JSON strings.

JSON has no serialization for infinity, not a number, and negative 0, therefore if you try and serialize INF, -INF, NaN, or -0 as JSON, an exception is thrown. If you want to represent these values in some way in your serialized JSON, then you can catch the exception (with a try/catch, for example) and provide your own value for it.

XQuery maps (map:map types) serialize to JSON name-value pairs.

  xdmp.toJsonString(["a",false]);
   => ["a", false]

xdmp.toJsonString(
  xdmp.fromJsonString('{ "a":111 }'));
=>
{"a":111}
