In this script:

$('mySelect option') selects all option elements within the select element with the ID mySelect.

.each(function() {...}) iterates through each option.

$(this).val() retrieves the value of the current option.

$(this).text() retrieves the text of the current option.

Step 4: Store Options in an Array (Optional)

If you want to store the options in an array for further manipulation, you can modify the script as follows:
