+```cpp
+using default_object_comparator_t = std::less<StringType>;  // until C++14
+
+using default_object_comparator_t = std::less<>;            // since C++14
+```
+
+The default comparator used by [`object_t`](object_t.md).
+
+Since C++14 a transparent comparator is used which prevents unnecessary string construction
+when looking up a key in an object.
+
+The actual comparator used depends on [`object_t`](object_t.md) and can be obtained via
+[`object_comparator_t`](object_comparator_t.md).
+
+## Examples
+
+??? example
+
+    The example below demonstrates the default comparator.
+
+    ```cpp
+    --8<-- "examples/default_object_comparator_t.cpp"
+    ```
+    
+    Output:
+    
+    ```json
+    --8<-- "examples/default_object_comparator_t.output"
+    ```
