javascript - 如何从字符串中获取字符数组？

Question

如何在 JavaScript 中将字符串转换为字符数组？

我正在考虑将 "Hello world!" 之类的字符串放入数组
['H','e','l','l','o','','w','o','r','l','d','!' ]

Note: This is not unicode compliant. "I💖U".split('') results in the 4 character array ["I", "�", "�", "u"] which can lead to dangerous bugs. See answers below for safe alternatives.

只需将其拆分为空字符串即可。

var output = "Hello world!".split('');
console.log(output);

见 String.prototype.split() MDN docs .
