    var superBlinders = [ ["Firelight", 4000], ["Solar Death Ray", 6000], ["Supernova", 12000] ];
    var lighthouseRock = {
      gateClosed: true,
      bulbs: [ 200, 500, 750 ],
      capacity: 30,
      secretPassageTo: "Underwater Outpost"
    };
    delete lighthouseRock.bulbs;
    lighthouseRock.weaponBulbs = superBlinders;
    console.log(lighthouseRock.weaponBulbs[2][0]);

    PIRATES AHOY! Despite protests of “I’m a coder, not a fighter”, it’s time for the ranger-devs to get over to the Lighthouse and throw down!

    In the editor is a modified object literal for Lighthouse Rock, with the new blinders now showing up in a property. Additionally, a new property, numRangers, has been added to track how many rangers are fighting for the Ocean of Objects at the Lighthouse.

    Your goal is to build a declared function that adds the following three rangers, in order and as complete objects, to the Lighthouse Rock object itself:

    1. name: “Nick Walsh”, skillz: “magnification burn”, station: 2
    2. name: “Drew Barontini”, skillz: “uppercut launch”, station: 3
    3. name: “Christine Wong”, skillz: “bomb defusing”, station: 1

    Each added ranger object should become its own property within lighthouseRock, specifically ranger1ranger2, and ranger3. Additionally, as you add a ranger, increment the number of rangers present using the existing numRangers property.

    In order to add your newly created objects to the Lighthouse, your function should accept a location parameter, which will represent that object. To help us check your function, order your function parameters as locationnameskillz, and station.

    Name your new function addRanger. Lastly, when the function has been built, call it three times, with the appropriate data each time, to effectively add all three rangers to lighthouseRock.

    var superBlinders = [ ["Firestorm", 4000], ["Solar Death Ray", 6000], ["Supernova", 12000] ];
    var lighthouseRock = {
      gateClosed: true,
      weaponBulbs: superBlinders,
      capacity: 30,
      secretPassageTo: "Underwater Outpost",
      numRangers: 0
    };
    function addRanger(location, name, skillz, station){
      location.numRangers++;
      location["ranger" + location.numRangers] = {name: name, skillz: skillz, station: station};
    }
    addRanger(lighthouseRock, "Nick Walsh", "magnification burn", 2);
    addRanger(lighthouseRock, "Drew Barontini", "uppercut launch", 3);
    addRanger(lighthouseRock, "Christine Wong", "bomb defusing", 1);
