Some candidates:

• Add optional length to functions accepting const char *
• new target for constructors
• named exports for ES6 modules - this one probably requires some design discussion first

[gabrielschulhof]

For convenience: napi_is_date() - on V8 it would be ->IsDate(), and on ChakraCore it would be napi_instanceof() after retrieving the "Date" property of the global object to obtain the constructor.

We're going to implement APIs on an as-needed basis, informed by the migration effort
