Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36051 [Changelog][Internal] This has been on my backlog for some time, submitting the diff to get it out of the way. It makes the macro-based code in the "iterator-based property parsing" branch somewhat less horrible and less error prone (by removing duplication vs the default values in the class declaration). Reviewed By: sammy-SC Differential Revision: D42990595 fbshipit-source-id: e4b91160c6e09d3d1eab2ba70a58d390243bb335
