如何从数组垂直打印字符串元素? [英] How to print string elements from an array vertically?

问题描述

我有一个数组，我想垂直打印每个元素.例如:

I have an array and I want to print every element vertically. For example:

myArr = ['abc', 'def','ghi'];

输出应为:

a d g

b e h

c f i

我已经通过使用2 for循环在php中做到了这一点，但是我在JS中执行相同的任务时遇到了麻烦.有什么建议么?

I've managed to do that in php by using 2 for loops but I'm having trouble with the same task in JS. Any suggestions?

推荐答案

可能的解决方案，带有两个循环.然后，您可以将其放到某些文本区域或任何您喜欢的区域中.

Possible solution, with two loops. Then you can just drop it inside some textarea or whatever you like.

const myArr = ['abc', 'def','ghi'];
const r = myArr.map((elem, i) => elem.split('').map((_, a) => myArr[a][i]).join(' ')).join('\n');
console.log(r);
