javascript - Dynamic variable name in loop

Question

I need to create dynamic variable name in js inside for loop

var counter = 0;
for(i=0; i<location.length; i++) {
   ...
   var "marker_" + counter = new google.maps.Marker({

But when i expected to have variables marker_0,marker_1,marker_2,... i had this error

Error: SyntaxError: missing variable name
Source Code:
          var "marker_" + counter = new google.maps.Marker({ 

Answer 1

Use an array:

var marker = [];

for (i=0; i < location.length; i++) {
   marker[counter] = new google.maps.Marker({
