/* String.charCodeAt(index) vs String.codePointAt(index) */
// Both methods return an integer representing the UTF-16 code.
'ABC'.charCodeAt(2); // → 67
'ABC'.codePointAt(2); // → 67
/* However, charCodeAt doesn't provide a full character code for
values greater than 0xFFFF, only the first part of a surrogate pair.
This is common for emoji. */
"{horse emoji}".charCodeAt(0); // → 55357
"{horse emoji}".codePointAt(0); // → 128052
/* (Displaying emoji not currently supported
by Grepper, so use your imagination above.) */
