toLocaleStringbeginner// Get locale-aware string representation
const date = new Date(2024, 0, 1)
date.toLocaleString() // β locale-specific date string
const num = 1234567
num.toLocaleString() // β '1,234,567'Use toLocaleString() to get a locale-sensitive string representation of a value, most useful on Date and Number objects.
Numbers have their own toLocaleString() that formats the number according to locale conventions (e.g., thousands separators).
Challenge: Use Number.prototype.toLocaleString and verify it returns a string.
