How to connect JavaScript and Html

So i want to connect my array from javaScript to my html, some one can explain how can i do that? i am only able to find when the javascript is in the same html.

html file: rest of the code in html ...

    <label for="eye">Which eye color does the character have?</label>
    <select name="eye" id="eye">
  <option value="blue">Blue</option>
  <option value="brown">Brown</option>
  <option value="green">Green</option>
</select>

<script>
    src = "js/eindopdracht.js"
</script>

js file:

var eyeColors = ["blue", "brown","green"];

the correct tag for you to use is is:

<script src="js/eindopdracht.js"></script>

this is how to include an external javascript file.

If you want to add javascript code inline then you would do:

<script>
  console.log("this is inline javascript");
</script>
