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.
Just split it by an empty string.
var output = "Hello world!".split('');
console.log(output);See the String.prototype.split() MDN docs.
As hippietrail suggests, meder's answer can break surrogate pairs and misinterpret “characters.” For example:
// DO NOT USE THIS!
const a = '𝟘𝟙𝟚𝟛'.split('');
console.log(a);
// Output: ["�","�","�","�","�","�","�","�"]I suggest using one of the following ES2015 features to correctly handle these character sequences.
