Почему JS делает неверные сравнения?

for (var i = 0; i < parseResult.length; i++) {
                var square = parseResult[i].square;
                var price  = parseResult[i].price;

                if (square > maxSquare) maxSquare = square;
                if (square < minSquare) minSquare = square;
                
                if (price > maxPrice) maxPrice = price;
                if (price < minPrice) minPrice = price;

                console.log('Price: ', price, ' > ', 'MaxPrice: ',maxPrice, ' ',price > maxPrice, 'Price: ', price, ' < ', 'MinPrice: ',minPrice, ' ', price < minPrice)
            }
