From this initialize array:
x = []
y = [1,2,3,4,5]
z = ["a", "b", "c", "d", "e"]
I want x result to be like this:
=> [[1,"a"], [2,"b"], [3,"c"], [4,"d"], [5,"e"]]
Is there any short method to do this without using nested loop?

2`y.zip(z)` #=> [[1, "a"], [2, "b"], [3, "c"], [4, "d"], [5, "e"]] – Konstantin Strukov Nov 10 '22 at 10:12

[y, z].transpose # => => [[1, "a"], [2, "b"], [3, "c"], [4, "d"], [5, "e"]] or z.map.with_index { |_, idx| [y[idx], z[idx]] } # => same response – Alireza mohagheghi Nov 10 '22 at 12:40
