getByPath
Traverses this JsonElement using a slash-delimited path (e.g., "a/b/c").
Extension function on JsonElement. Empty segments are ignored. Unlike get, . is not a separator, so this also reaches keys that contain a dot.
Return
the JsonElement at the given path, or null if any key is missing or the path runs into a value that is not an object. A key that is present with a JSON null value is returned as JsonNull.
Parameters
path
a /-separated path of object keys
