This task can be split basically by file. The re-implementation consists of going over every node_xxx file in the src directory and rewriting it to use Napi. Here is a list of all files that should be visited

• [x] js_adapter.hpp
• [x] js_global_notifier.hpp
• [x] node_class.hpp
• [x] node_context.hpp
• [x] node_dummy.cpp
• [x] node_exception.hpp
• [x] node_function.hpp
• [x] node_init.cpp
• [x] node_init.hpp
• [x] node_napi_convert.hpp
• [x] node_object.hpp
• [x] node_protected.hpp
• [x] node_return_value.hpp
• [x] node_string.hpp
• [x] node_types.hpp
• [x] node_value.hpp
• [x] platform.cpp
• [x] sync_logger.cpp
• [x] sync_logger.hpp
• [x] Visit implementation and add EscapableHandleScopes where needed (more than one napi value created)
• [x] Handle and remove all //NAPI: comments
• [x] Remove all nan.h, v8.h references
• [x] Tidy up implementation (if needed)
• [x] Test for node 12 issues
• [x] Make CI work (jenkins, docker)
• [x] Minimal Benchmark ( run adapter benchmark)
• [ ] RN class syntax support changes 

These tasks can change over the course of the reimplementation.
