 - **Zero-copy**: cross-language out-of-band serialization inspired
   by [pickle5](https://peps.python.org/pep-0574/) and off-heap read/write.
 - **High performance**: A highly-extensible JIT framework to generate serializer code at runtime in an async multi-thread way to speed serialization, providing 20-170x speed up by:
-    - reduce memory access by inline variable in generated code.
+    - reduce memory access by inline variables in generated code.
     - reduce virtual method invocation by inline call in generated code.
     - reduce conditional branching.
     - reduce hash lookup.
-- **Multiple binary protocols**: object graph, row format and so on.
