React Native render for draft.js and react-draft-wysiwyg but has some bugs, I fixed for my personal project

export default function generateKey(): Number {
  function s4() {
    return Math.floor((1 + Math.random()) * 0x10000)
      .toString(16)
      .substring(1);
  }
  return `${s4()}${s4()}-${s4()}-${s4()}${s4()}-${s4()}${s4()}-${s4()}${s4()}${s4()}`;
}
