 * @param  {H.Map} map A HERE Map instance within the application
function setStyle(map){
  // get the vector provider from the base layer
  var provider = map.getBaseLayer().getProvider();
  // Create the style object from the YAML configuration.
  // First argument is the style path and the second is the base URL to use for
  // resolving relative URLs in the style like textures, fonts.
  // all referenced resources relative to the base path https://js.api.here.com/v3/3.1/styles/omv.
  var style = new H.map.Style('https://heremaps.github.io/maps-api-for-javascript-examples/change-style-at-load/data/dark.yaml',
  // set the style on the existing layer

 * Boilerplate map initialization code starts below:

//Step 1: initialize communication with the platform
// In your own code, replace variable window.apikey with your own apikey

var platform = new H.service.Platform({
  apikey: window.apikey
var defaultLayers = platform.createDefaultLayers();

//Step 2: initialize a map
var map = new H.Map(document.getElementById('map'),
  defaultLayers.vector.normal.map, {
  center: {lat: 52.51477270923461, lng: 13.39846691425174},
  zoom: 13,
  pixelRatio: window.devicePixelRatio || 1
// add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());

//Step 3: make the map interactive
// MapEvents enables the event system
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));

// Now use the map as required...

        <p>Set a style of the whole map during the map instantiation</p>
    <p>This example shows how to set a map style during the map loading. The vector layer uses the 'normal.day' style by default, the style
      can be changed to the user defined while the map is loading.
    <div id="map"></div>
    <p>The code below created a new <codeph>H.map.Style</codeph> instance that loads and parses the user's style 'dark.yaml'. After that
      the style is set on the current vector provider.
