我们需要编写一个JavaScript函数,该函数接受一个字符串和一个数字n(以使n精确地划分字符串的长度),并且我们需要返回一个长度为n的字符串数组,其中包含n个相等的部分。
为此的代码将是-
const str = 'we will be splitting this string into parts'; const num = 6; const divideEqual = (str, num) => { const len = str.length / num; const creds = str.split("").reduce((acc, val) => { let { res, currInd } = acc; if(!res[currInd] || res[currInd].length < len){ res[currInd] = (res[currInd] || "") + val; }else{ res[++currInd] = val; }; return { res, currInd }; }, { res: [], currInd: 0 }); return creds.res; }; console.log(divideEqual(str, num));
输出结果
控制台中的输出-
[ 'we will ', 'be split', 'ting thi', 's string', ' into pa', 'rts' ]
