Merge 2 arrays into same index value

Question

Say i have the two following arrays

array_1 = ["Person One", "Person Two", "Person Three"]
array_2 = ["24", "25", "26"]

How would I merge these arrays together so that the output would be

["Person One 24", "Person Two 25", "Person Three 26"]

Thanks

Use zip and join:

array_1.zip(array_2).map { |a| a.join(' ') }

You can do it following way:

array_1.each_with_index.map{ |el, i| el + " " + array_2[i].to_s }
# => ["Person One 24", "Person Two 25", "person Three 26"]

array_1.zip(array_2).map { |a1, a2| "#{a1} #{a2}" }
#⇒ ["Person One 24", "Person Two 25", "Person Three 26"]
