Passing array data from php to javascript using a loop

Is there a similar way to implement this kind of "algorithm" in the right way? 

for(i=0;i<howManyCourses;i++){

            var stored = "<?php echo $buf[i] ?>";
            var option = document.createElement("option");
            option.text=stored;
            e.add(option);

        }

So I want to pass the data from the $buf array into a javascript variable. I've tried many ways but it seems like I cannot find the solution. I'm new into php and I apologise for any obvious mistake.

It should be in the same file or in another case AJAX will be the solution. 

<script type="text/javascript">

       const arr = <?php echo json_encode($buf); ?>;

       for (var i = 0; i < arr.length ; i++) {
           //do something
       }

 </script>

If you need that JS' variable buf contain the same elements as PHP's $buf, you can do the following:

var buf = <?php echo json_encode($buf); ?>;

Just keep in mind that if PHP's $buf is not an indexed array, JS' buf will be an object instead of an array.
