?
????????????// Adding the markers
????????????var marker = new google.maps.Marker({
????????????????position: places[i],

????????????????title: ‘Place number ‘
+ i
????????????});
?
????????????// Wrapping the event listener inside an anonymous function

?
????????????????// Creating the event listener. It now has access to the values of

?
????????????????????if (!infowindow) {
