循环数组以显示重复第 n 次的数组字符串

问题描述

使用下面的数组，我需要一个循环来获得下面给出的特定结果：

var arr = ["ABCDE","BCDEF","BACDF","ACDLK","ABDCDE","CDCDE"];

每次重复一次，数组结果为一个空格。结果应如下所示：

["ABCDE","CDCDE","ABCDE ","BCDEF ","BACDF ","ACDLK ","ABDCDE ","CDCDE ","ABCDE  ","BCDEF  ","BACDF  ","ACDLK 
 ","ABDCDE  ","CDCDE  "]

解决方法

您可以使用闭包并将后缀添加到值中。

const
    suffix = '*',getArray = (array,length) => Array
        .from(
            { length },(_,i) => array.map(s => s + suffix.repeat(i))
        )
        .flat(),result = getArray(['a','b','c'],4);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
