I am trying to extract metadata from a website. More specifically, the description tag. This is my code so far:

    <p><input id="submittedURL" type="text" placeholder="gimme that URL"></p>
    <p><button onclick="grabDesc()">Submit</button></p>
    <script>
        function grabDesc(){
            let desiredURL = document.getElementById("submittedURL").value;
    }
    </script>

Thanks.

Update: Went and ran my current code. No errors yet no results. -> I would like to know how to extract the content of the description tag from desiredURL.
