Hi Joe,

To access a Ruby array index in Javascript, you can convert your Ruby array to JSON. Here is how you can do it:

<script type="text/javascript">
  var array = <%= raw ruby_array.to_json %>;
  console.log(array[0]);  // Access first element
</script>

This script converts the ruby_array to a JSON array that can be used in Javascript. Hope this helps!

Best,

I tried this, but it’s not returning the elements of the array, just character in the string.
