Combine two Arrays into Hash

Question

I\'ve got two Arrays:

members     = [\"Matt Anderson\", \"Justin Biltonen\", \"Jordan Luff\", \"Jeremy London\"]
instruments = [\"guitar, vocals\", \"guitar\         


        

Answer 1

members.inject({}) { |m, e| t = instruments.delete_at(0).split(','); m[e] = t.size > 1 ? t : t[0]; m }

If you don't care about 1-element arrays in the result, you can use:

members.inject({}) { |m, e| m[e] = instruments.delete_at(0).split(','); m }
