问题 Is there a way to take a recursive function (like the following) and make it tail recursive? I have an input like this: { "message": "Test ", "read": [ { "test": " t " } ] } and this Dataweave function fun trimWS(item) = item match { case is Array -> $ map trimWS($) case is Object -> $ mapObject { ($$): $ match { case is String -> trim($) case is Object -> trimWS($) case is Array -> $ map trimWS($) else -> $ } } case is String -> trim($) else -> $ } 回答1: I reworked a little bit your existing
