合并Ruby数组并连接其中的元素

我有两个数组

arr1 = ["a","b","c","d"]
arr2 = ["e","f","g","h"]

我想得到这样的结果

arr3 = ["ae","bf","cg","dh"]

我如何在ruby中做到这一点？

我会使用：

我也这么做了。。。但你总是跑得更快！：）使用

zip/join

似乎是显而易见的解决方案。不知道为什么会被否决。使用这个arr1.map.with_index{e，i | e+arr2[i]}因为它更快，在这里可以看到相同的问题

arr1 = ["a","b","c","d"] 
arr2 = ["e","f","g","h"]
arr1.zip(arr2).map(&:join)
# => ["ae", "bf", "cg", "dh"]
