Arrange Javascript Arrays

Question

I have array of cars and an array of price corresponding to each car.

I want to implement the function highest3 which will return an array of 3 cars in order by their p

Answer 1

This is only one possible solution:

//I assume you get the arrays correctly linked i.e price[0] is the 
//price of cars[0]
var cars = ["Ferrari", "Lamborghini", "Jaguar", "Hummer", "Toyota"];
var price = [12, 34.5, 3.54, 45.9, 3.44];

result == ["Hummer", "Lamborghini", "Ferrari"];

function highest3 (cars, price) {

//First we unite the two arrays 
carsAndPrice = [];
for (var i = 0; i < cars.length; i = i +1)
    carsAndPrice[i] = {car:cars[i],price:price[i]};
}
//Now that the price and the cars are strongly linked we sort the new array
//I'm using bubble sort to sort them descending this seems to be more of 
//a beginner question
var swapped;
    do {
        swapped = false;
        for (var j=0; j < carsAndPrice.length-1; i++) {
            if (carsAndPrice[i].price < carsAndPrice[i+1].price) {
                var temp = carsAndPrice[i];
                carsAndPrice[i] = a[i+1];
                carsAndPrice[i+1] = temp;
                swapped = true;
            }
        }
    } while (swapped);
  //return the name of the first 3 cars from the array
  var result = [];
  result[0] = carsAndPrice[0].price; //Most expensive
  result[1] = carsAndPrice[1].price;
  result[2] = carsAndPrice[2].price;
  }
