julia - How to find the key for the min/max value of a Dict?

Question

I want to find the key corresponding to the min or max value of a dictionary in julia. In Python I would to the following:

my_dict = {1:20, 2:10}
min(my_dict, my         


        

Answer 1

another option is:

collect(keys(d))[indmin(collect(values(d)))]

it depends on properties of keys and values iterators which are not guaranteed, but in fact work for Dicts (and are guaranteed for OrderedDicts). like the reduce answer, d must be non-empty.

why mention this, when the reduce, pretty much nails it? it is 3 to 4 times faster (at least on my computer) !
