🤣 😂

Emojis in code? Why not?

let a = 0;

a += '🤣'.charCodeAt(0)-'😂'.charCodeAt(0) // a = 1

Explanation

• First of all, emojis are different to normal text. Emojis UTF-16 encoding is greater than 16 bits, so "😀".length will return 2 (and "😀".split('') will return 2 symbols).
• In the code above we just get codes of first emojis symbols (55358 and 55357).

PS. codePointAt method is preferable for handling emojis (instead of charCodeAt).
