I want to make a form in HTML that asks your name, last name and country.
Names are no problems, but countries are. I want (need) to use a dropdown list with all the countries of the world, the options of the dropdown list are all elements from a javascript array.

The way I made the js file is like this: i made a function init(){
let list_countries=['afghanistan',...] so I made a var list_functions with all the countries, after that I ran the function
init().

The thing is, how can I represent each of these countries as an option in my dropdown list? I'd like to do this part of coding in html tags

What I have tried:

I tried things like:

HTML

<select id="country_list"></select>
    <script src="script.js">
    </script> 
</select><br></br>

I tried swapping select and script etc, but I have no clue :/

I tried googling/finding the solution online, but I can't find a perfect solution to my question.

Here's the idea:

HTML

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title></title>
<script type="text/javascript">
  function countries_ddl() {
     var countries = ["England", "France", "Germany"];
     var select = document.getElementById('country_list');
     for (var i = 0; i < countries.length; i++) {
        var opt = document.createElement('option');
        opt.value = i;
        opt.innerHTML = countries[i];
        select.appendChild(opt);
     }
}
</script>
</head>
<body onload="countries_ddl()">
		<select id="country_list">
         <option value="0">- please select -</option>
		</select>		
</body>
</html>
