  <pre><code> `     render() {
              &lt;div&gt;
              &lt;MapWithAMarker markers={this}
              googleMapURL="https://maps.googleapis.com/maps/api/js?
              key=key&amp;v=3.exp&amp;libraries=geometry,drawing,places"
              loadingElement={&lt;div style={{ height: `100%` }} /&gt;}
              containerElement={&lt;div style={{ height: `100vh` }} /&gt;}
              mapElement={&lt;div style={{ height: `100%` }} /&gt;}
              /&gt;}&lt;/div&gt; }
  
             const MapWithAMarker = compose(
             withScriptjs,
             withGoogleMap)(function(that) { 
             &lt;GoogleMap
              center={{lat: parseFloat(props.currentLocation.lat), lng: 
              parseFloat(props.currentLocation.lng) }}

              parseFloat(props.currentLocation.lat), lng: 
              parseFloat(props.currentLocation.lng) }}
