Is it better to use
obj == nil
Is it better to use obj.nil? or obj == nil
It is exactly the same. It has the exact same observable effects from the outside ( pfff ) *
and what are the benefits of both.
If you like micro optimizations all the objects will return
false to the
.nil? message except for the object
nil itself, while the object using the
== message will perform a tiny micro comparison
with the other object to determine if it is the same object.
* See comments.
