Hello,
How can I simply build one hash from two arrays. One containing keys
and second containing values.
keys = [‘a’, ‘b’, ‘c’]
vals = [1, 2, 3]
h = {‘a’=>1, ‘b’=>2, ‘c’=>3}
No matter how far down the wrong road you’ve gone, turn back.

How can I simply build one hash from two arrays. One containing keys
and second containing values.keys = [‘a’, ‘b’, ‘c’]
vals = [1, 2, 3]h = {‘a’=>1, ‘b’=>2, ‘c’=>3}
After sending question I found this solution
keys = res.fields
vals = res.result[0]
h = Hash.new(nil)
0.upto(keys.length) do |i|
h[keys[i]] = vals[i]
end
return h
but, could it be simpler?

Assuming a one-to-one correspondence between keys[0] and vals[0],
keys[1] and vals[1], etc:
keys.each_index { |k| h[keys[k]] = vals[k] }
