// Welcome to the Mapbox Geography game workshop! You've downloaded
// right file: you should be looking at this in your text editor.

// We already have a few things defined that you should be aware of:
// mapboxgl: the Mapbox GL JS library, the way you'll show maps
// names: a list of the names of all the countries
// boundsByName: an object that gives you the bounds of each country
// buttons: the container, a div element, for the buttons

// The first step is replacing YOUR-ACCESS-TOKEN-HERE with your access
// token. You can find your access token in Mapbox Studio on the right-hand
// side.
mapboxgl.accessToken = 'YOUR-ACCESS-TOKEN-HERE';

var map = new mapboxgl.Map({
    container: 'map',
    style: 'mapbox://styles/mapbox/satellite-v8',
    center: [0, 0],
    zoom: 3
});

// Here are the steps:

// 1: adding a single country, the United States, in orange on the map.
// 2: choosing three countries from the list of countries from the names variable
// 3: highlighting the first country we choose
// 4: zooming to the first country we choose, by using boundsByName
// 5: adding a button for each of the three countries we choose
// 6: adding the name of the country and an onclick function to each button
// 7: determining whether you've clicked the right country
// 8: choosing countries at random
// 9: randomizing the buttons as well
// 10: make the game start again if you win!

map.on('style.load', function() {
  // Your code will go below this line!

});
