Synchronous APIs are easier to use since it's how things have been done
since decades ago, but I don't think they fit in a event-oriented
environment like Javascript, and more specially to some so time consuming
like filesystem and IO. I find it better to only develop asynchronous APIs
for this use cases. It would make sense to use synchronous APIs to help
porting current code for example from C/C++ to Javascript, but the required
POSIX-like APIs would be better developed as external libraries on top of
the asynchronous ones.
