I've some questions about destructuring a seq of maps, like:
1. Is it possible?
2. If yes, does it have any sense?
3. And if it's possible and is reasonable, how can I do it?
For example, let's say that I have a list of maps like this:
(def something [{:a 1 :b 2}
{:a 2 :b 5}
{:a 3 :b 7}])
And let's say that I want a function that returns the sum of all :a
values of the something seq. I could write the function in this way:
(defn do-sum [some-coll]
(reduce + (map #(:a %) some-coll)))
Not a big deal, but I wonder if there is a better way to do it.
Destructuring could be one answer I thought, since I need only the value
corresponding to the :a key of every map in the seq. But I didn't
figured out how to do it yet.
Any ideas?
