toLocaleString() — custom override

📖 Usage Example
// Get locale-aware string representation
const date = new Date(2024, 0, 1)
date.toLocaleString()   // → locale-specific date string
const num = 1234567
num.toLocaleString()    // → '1,234,567'

Use toLocaleString() to get a locale-sensitive string representation of a value, most useful on Date and Number objects.

toLocaleString() — custom override

You can override toLocaleString() on your own objects to return a custom locale-aware string.

Challenge: Create an object with a custom toLocaleString() that returns a specific string.
