String.prototype.codePointAt() — emoji code point

📖 Usage Example

const str = 'Hello'
str.codePointAt(0)     // → 72
'😀'.codePointAt(0)    // → 128512

Use codePointAt() to get the full Unicode code point at a position, correctly handling supplementary characters.

String.prototype.codePointAt() — Supplementary Characters

For emoji and other supplementary characters, .codePointAt(0) returns the full code point (e.g. 128512 for 😀).

Challenge: Implement emojiCodePoint() that returns the code point of '😀' at position 0.

emojiCodePoint() // → 128512
