Basic JavaScript function

Okay so I am trying to separate the two words within the same string using a function. Here is my code...

var carArray = ["Jeep Wrangler", "Toyota Land Cruiser", "Land Rover Range Rover"];

function makeModel(carArray) {
  return ????????????????????????;
  }

I want to return the input array by breaking up the first string into individual words. So instead of "Jeep Wrangler" it would return "Jeep" and "Wrangler"

If you have any suggestions please help, thanks!!

You have a real tricky problem on your hands. Using the split method, as mentioned before, will only work for make/model pairs that are represented by single words (i.e. "jeep", "wrangle"). When you get to "Land Rover", "Range Rover", for example, the split method quickly presents a problem. You will end up with an array like this: ['Land', 'Rover', 'Range', 'Rover']. The biggest problem is that you don't have any defined number of array elements that describe the make section and a defined number of elements that define the model section. You will probably need to implement some type of hash table that defines the possible makes of cars: ["Jeep", "Toyota", "Land Rover"], and split the string based on that. Maybe doing something like:

function makeModel(car) {
  var models = new Array('Jeep', 'Toyota', 'Land Rover');
  returnObj = {};

  models.forEach(function(element) {
    if (car.indexOf(element) === 0) {
      returnObj = {
        make: element,
        model: car.slice(element.length)
      }
    };
  });
  return returnObj;
};

This could probably be refined quite a bit, but hopefully it will give you some direction.

You probably want the split method. So iterate your array with car.split(" "), use a for or foreach to loop through the array.

if you use the split methode you'll get the two seperate words in an array. I don't know if that's what you meant. type the model's index as an argument for the makeModel function :)

var carArray = ["Jeep Wrangler", "Toyota Land Cruiser", "Land Rover Range Rover"];
function makeModel (idx){
  var model = carArray[idx].split(" ");
  return model;
}
