Note: This is not unicode compliant.

(注意：这不符合unicode。)

"I??U".split('') results in the 4 character array ["I", " ", " ", "u"] which can lead to dangerous bugs.

("I??U".split('')导致4个字符数组["I", " ", " ", "u"] ，这可能导致危险的错误。)

Just split it by an empty string.

(只需将其拆分为空字符串即可。)

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

See the String.prototype.split() MDN docs .
