String.prototype.charAt() — middle character

📖 Usage Example

const str = 'Hello'
str.charAt(0)    // → 'H'
str.charAt(1)    // → 'e'
str.charAt(99)   // → ''

Use charAt() to get the character at a specific index, returning an empty string for out-of-bounds positions.

String.prototype.charAt() — Middle

Challenge: Implement midChar(str) using .charAt() to return the middle character of an odd-length string.

midChar('hello') // → 'l'
midChar('abc')   // → 'b'
