✅ Solution & explanation
$json.products.sort((a, b) => a.price - b.price)
Output: Lite, Pro, Team
sort() calls the compare function for pairs of items. Returning a.price - b.price is negative when a is cheaper, so it moves first. Without a compare function, numbers are sorted as text (100 before 9).💡 Pro tip: Reverse the order (high → low) with b.price - a.price.
