我想在左条件下实现多个单词

var word1 = "我";
var word2 = "想";
var word3 = "实现";
var word4 = "多个";
var word5 = "单词";

var result = word1 + word2 + word3 + word4 + word5;
console.log(result); // 输出：我想实现多个单词

var words = ["我", "想", "实现", "多个", "单词"];

var result = words.join("");
console.log(result); // 输出：我想实现多个单词
