XE질문 이라기보다 js질문입니다

OpenLayers3 를이용하여 지도사이트를 만드려고 하는중인데

사이트에서 제공하는 샘플소스

=======샘플소스======

<!doctype html>
<html lang="en">
  <head>
    <link rel="stylesheet" href="http://openlayers.org/en/v3.18.2/css/ol.css" type="text/css">
    <style>
      .map {
        height: 400px;
        width: 100%;
      }
    </style>
    <script src="http://openlayers.org/en/v3.18.2/build/ol.js" type="text/javascript"></script>
    <title>OpenLayers 3 example</title>
  </head>
  <body>
    <h2>My Map</h2>
    <div id="map" class="map"></div>
    <script type="text/javascript">
      var map = new ol.Map({
        target: 'map',
        layers: [
          new ol.layer.Tile({
            source: new ol.source.OSM()
          })
        ],
        view: new ol.View({
          center: ol.proj.fromLonLat([37.41, 8.82]),
          zoom: 4
        })
      });
    </script>
  </body>
</html>

=========

이 소스를 html파일따로 css파일따로 js파일따로 만들어서 html에서 불러오려고 소스를 수정해봤습니다

====index.hmtl===

<!doctype html>
<html lang="en">
<head>
<link rel="stylesheet" href="http://openlayers.org/en/v3.18.2/css/ol.css" type="text/css">
<link rel="stylesheet" type="text/css" src="css.css">
<script src="http://openlayers.org/en/v3.18.2/build/ol.js" type="text/javascript"></script>
<title>OpenLayers 3 example</title>
</head>
<body>
<h2>My Map</h2>
<div id="map" class="map"></div>
<script src="http://openlayers.org/en/v3.18.2/build/ol.js" type="text/javascript"></script>
<script type="text/javascript" src="js.js"> </script>
</body>
</html>

========css.css======

=====js.js=====
var map = new ol.Map({
target: 'map',
layers: [
new ol.layer.Tile({
source: new ol.source.OSM()
})
],
view: new ol.View({
center: ol.proj.fromLonLat([37.41, 8.82]),
zoom: 4
})
});

이렇게 원본파일을 수정했는데 js 파일에서 오류가납니다

1'ol' was used before it was defined.var map = new ol.Map({4Expected 'new' at column 13, not column 11.new ol.layer.Tile({5Expected 'source' at column 17, not column 13.source: new ol.source.OSM()6Expected '}' at column 13, not column 11.})9Expected 'center' at column 13, not column 11.center: ol.proj.fromLonLat([37.41, 8.82]),10Expected 'zoom' at column 13, not column 11.zoom: 412Expected '}' at column 5, not column 7.});

아마 js.js파일에서 http://openlayers.org/en/v3.18.2/build/ol.js 를 임포트시켜야될거같은데 어떻게 해야할지 알려주시면 감사하겠습니다
