 The special case of `null` as `"null"`, aka `"\"null\""`:
 
+```
+typeof null        // object
+typeof "null"      // string
+typeof "\"null\""  // string
+```
+
 `null`, and `"null"` both parse as `null` the "object", instead of one being the string (which would be `"\"null\""`).
 
+```
+JSON.parse(null)       // null (object)
+JSON.parse("null")     // null (object)
+JSON.parse("\"null\"") // 'null' (string)
+```
+
 Objects containing `null`, however, parse as expected `{ "foo": null, "bar": "null" }` will parse as `foo` being `null` but `bar` being `"null"`, much unlike the value `"null"` being parsed on its own.
+
+```
+JSON.parse('{ "foo": null }')    // { foo: null }
+JSON.parse('{ "foo": "null" }')  // { foo: 'null' }
+```
