How to split Unicode string to characters in JavaScript

Question

For long time we used naive approach to split strings in JS:

someString.split('');

But popularity of emoji forced us to change this approach - emoji characters (and other non-BMP characters) like 😂 are made of two "characters'.

String.fromCodePoint(128514).split(''); // array of 2 characters; can't embed due to StackOverflow limitations

So what is modern, correct and performant approach to this task?

Answer 1

Using spread in array literal :

const str = "🌍🤖😸🎉";
console.log([...str]);

Using for...of :

function split(str){
  const arr = [];
  for(const char of str)
    arr.push(char)
   
  return arr;
}

const str = "🌍🤖😸🎉";
console.log(split(str));
