+property to remove is an element in an array.
+    To remove `adserver` object properties from array in following JSON payload:
+
+        {"playlist": [{"adserver": "first"},{"adserver": "second"}]}
+
+    Use:
+
+        +js(json-prune, playlist.[].adserver)
+
+- `*` - will iterate through all own properties of an object. For example, to deal with hard to predict random-named properties.
+    To remove `adserver` object properties from inside _randomly named_ objects in following JSON payload:
+
+        {"playlist": {"random1": {"adserver": "first"}, "randomB": {"adserver": "second"}}}
+
+    Use:
+
+       +js(json-prune, playlist.*.adserver)
