I tried running the following in a html file on my computer. It didn't load. Can anyone tell me where I messed up

<!DOCTYPE html>
    <title>Simple Map</title>
    <meta name="viewport" content="initial-scale=1.0">
    <meta charset="utf-8">
      /* Always set the map height explicitly to define the size of the div
       * element that contains the map. */
      #map {
        height: 100%;
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
    <div id="map"></div>
      var map;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: -34.397, lng: 150.644},
          zoom: 8
    <script src="https://maps.googleapis.com/maps/api/js?key=[MY_API_KEY&callback=initMap"
    async defer></script>

Thanks in advance.

You need to replace the MY_API_KEY on line 32 with your own API KEY which you get from Here --> Google developers

It should look something like this AIbaTuC9zDy-MXQF3meyzRZXD1766VOcj2B5RE8

So that line should be

<script src="https://maps.googleapis.com/maps/api/js?key=[AIbaTuC9zDy-MXQF3meyzRZXD1766VOcj2B5RE8&callback=initMap" async defer></script>
