我们需要编写一个JavaScript函数,该函数接受一个字符串并将该字符串的相邻单词彼此交换,直到该字符串的结尾。
为此的代码将是-
const str = "This is a sample string only"; const replaceWords = str => { return str.split(" ").reduce((acc, val, ind, arr) => { if(ind % 2 === 1){ return acc; } acc += ((arr[ind+1] || "") + " " + val + " "); return acc; }, ""); }; console.log(replaceWords(str));
输出结果
控制台中的输出-
is This sample a only string
