开发笔记:交替合并字符串

1、代码

/**
* &＃64;param {string} word1
* &＃64;param {string} word2
* &＃64;return {string}
*/
let mergeAlternately &＃61; function(word1, word2) {
// 定义一个新数组
const arr &＃61; [];
// 把传进来的字符串克隆到数组中
const result1 &＃61; word1.split("");
const result2 &＃61; word2.split("");
// 使用 while 循环数组
// 并且两个数组的长度都不能为 0
while (result1.length && result2.length) {
arr.push(result1.shift());
arr.push(result2.shift());
};
return [...arr, ...result1, ...result2].join("");
};
console.log(mergeAlternately("ace", "bdf")); // abcdef
console.log(mergeAlternately("ace", "bdfghi")); // abcdefghi
console.log(mergeAlternately("acegi", "bdfh")); // abcdefghi
