I saw the {Emoji} and other Unicode character class escapes in some answers to achieve the goal, but no one explains how they work, which have been part of the baseline since July 2015:

• Unicode character class escape: \p{...}, \P{...} - MDN Docs
• Table 70: Binary Unicode property aliases and their canonical property names - ECMAScript Language Specification
• Table 71: Binary Unicode properties of strings - ECMAScript Language Specification
• UTS #51: Definitions - Unicode Emoji Docs

After reviewing the mentioned tables, the most promising one seems to be Extended_Pictographic:

• ED-4. extended pictographic charachter - Unicide Emoji Docs

function removeEmojis(str) {
  return str.replace(/[\p{Extended_Pictographic}]/gu, '');
}

let text = "Hello 🌍! This is a test with ❤️ and 123. 😃";
let cleanedText = removeEmojis(text);

console.log(cleanedText); // "Hello ! This is a test with  and 123."
