Javascript 从字符数组中生成变量

Question

如何从 Javascript 中的字符数组创建变量。

chars = ["a","b","c","d"];
chars[1],chars[0],chars[2] = "Hellow world";
alert(bac); // Hellow world

Answer 1

不需要eval或map:

var chars = ["a", "b", "c", "d"];
window[chars[1] + chars[0] + chars[2]] = "Hellow world";
console.log(bac); // Hellow world
