You could argue that this should be kInternalized.

Since we expect process.execPath to be long-lived, using internalized strings might make more sense. (It probably doesn’t matter all that much in individual cases like these, but the sum of the work we’re saving the GC might matter a bit.)

I think for everything in this header, kInternalized would make more sense as the string type.

t->SetClassName(fn_name);
recv->PrototypeTemplate()->Set(fn_name, t);
