+## Add JsonExtractor utility class
+
+We've added a new class to the `JSON` library. `JsonExtractor` bundles up a lot of the boilerplate needed to extract typed values from Json objects.
+
+Given the following Json:
+
+```json
+{
+  "name": "John",
+  "age": 30,
+  "isStudent": true
+}
+```
+
+Where you previously had to do:
+
+```pony
+let doc = recover val JsonDoc.>parse(src)? end
+let name = (doc.data as JsonOject).data("name")? as String
+let age = (doc.data as JsonOject).data("age")? as I64
+let isStudent = (doc.data as JsonOject).data("isStudent")? as Bool
+```
+
+You can now do:
+
+```pony
+let doc = recover val JsonDoc.>parse(src)? end
+let name = JsonExtractor(doc.data)("name")?.as_string()?
+let age = JsonExtractor(doc.data)("age")?.as_i64()?
+let isStudent = JsonExtractor(doc.data)("isStudent")?.as_bool()?
+```
+
+For simple Json structures such as the one above, there is little difference. However, once you start dealing with nested objects and arrays, `JsonExtractor` can save you a lot of boilerplate code.
