Hi all,
Often I need to make decisions in simple threading macros, for instance
consider the following code
(->> m
:vector
(filterv #(= (:id %) (:id m)))
(reduce #(and %1 %2)))
In this case, if the result of filter is empty reduce throws an exception
as it expects some values. Therefore, I want to include a decision between
filter and reduce for instance if empty then add false into the resulting
vector. What would be the best way to achieve this? I could add a function
that checks if empty then add sth into the vector but wanted to ask your
opinions if there is a better way to do this.
Regards,
Timur
