Need help comparing the search results against items in array, both loop and index of methods are breaking.

Here is my code, i appreciate your help. 

 var locations = [];
function station (city, fullAddress) {
  this.city = city;
  this.fullAddress = fullAddress;
  locations.push(this);
}
  var unionSqSea = new station ('seattle', "601 Union St, Seattle, WA 98101");
  var SheratonTac = new station ('tacoma', "234 Main St, Tacoma, WA 98109");
    console.log (unionSqSea); 

var tracker = {
  getForm: document.getElementById('search'),
  searchWord: null,

  getQueryData: function (event) {
    event.preventDefault();
    this.searchWord = event.target.searchName.value;
    var queryWord = this.searchWord.toLowerCase();
    console.log (queryWord); 

// this is 1st method to compare, but it is not working.
       for (var i = 0; i < locations.length; i++) {
         if (locations[i] === queryWord) {
           console.log('matched');
         }
       }

    // this 2nd method, and it is NOT working either, 

    // if (locations.indexOf(queryWord)) > - 1 {
    //   console.log('matched');
    //     }

      // if it matches, append the address to the page Here.
  },
}
tracker.getForm.addEventListener('submit',tracker.getQueryData);

In the first function, you just need to add .cityto locations[0] part in your loop condition. For the second one, locations.indexOf(queryWord) should be locations[i].city.indexOf(queryWord)

Michael, thanks for help. (locations[i].city === queryWord) appears to work on codepen, but not on atom. There is red dot next to for (var i = 0; i < locations.length; i++) Any idea why it is not working?

var locations = [];
function station (city, fullAddress) {
  this.city = city;
  this.fullAddress = fullAddress;
  locations.push(this);
}

  var unionSqSea = new station ('seattle', "601 Union St, Seattle, WA 98101");
  var SheratonTac = new station ('tacoma', "234 Main St, Tacoma, WA 98109");
    console.log (unionSqSea);

var tracker = {
  getForm: document.getElementById('search'),
  searchWord: null,


  getQueryData: function (event) {
    event.preventDefault();
    this.searchWord = event.target.searchName.value;
    var queryWord = this.searchWord.toLowerCase();
    console.log (queryWord);

       for (var i = 0; i < locations.length; i++) {
         if (locations[i].city === queryWord) {
           alert('match');
         }
       }

      // if it matches, append the address to the page Here.
  },
}
tracker.getForm.addEventListener('submit',tracker.getQueryData);
