This JavaScript program document.write () is not working?

I am learning how to use JavaScript and I am having trouble correctly displaying the url within the document.write() function. I am writing the program with an actual url in the "href" portion but I can not write it in this question since it is apparently prohibited to do so. Is there something that I am missing?

<!doctype HTML>
<html lang="en">

<head>
    <meta charset="utf-8">
    <title> Link Test </title>
</head>

<body>
    <a id="mylink" href="#"> Click me</a>
    <br>
    <script type="text/JavaScript">
        url = document.links.mylink.href document.write('The URL is ' + url)
    </script>
</body>

</html>

let url = document.links.mylink.href;
document.write('The URL is ' + link);

But still, I won't recommend using document.write method. You'd better add some html tag, where you can safely insert the result via innerHtml or innerText methods:

html:

<a id="mylink" href="#Test"> Click me</a>
<span id="result"></span>

js:

let url = document.links.mylink.href;
let result = document.getElementById('result');
result.innerText = url;

Remove type="text/JavaScript" part from your code. Some modern browsers will give you an error on it.

Also I suggest you to write your statements in separate lines. JS engine understands your whole line as a one statement. So it gives an error. I suggest you to separate lines and put ; at the end of each line or you can add ; after the statement, if you want to write in one line. And also define your variables with var or let and const in ES6.

<!doctype HTML>
<html lang="en">

<head>
    <meta charset="utf-8">
    <title> Link Test </title>
</head>

<body>
    <a id="mylink" href="#"> Click me</a>
    <br>
    <script>
        var url = document.links.mylink.href ;
        document.write('The URL is ' + url);
    </script>
</body>

</html>

You are missing a semicolon if you want to have it on one line. Like this:

url = document.links.mylink.href; document.write('The URL is ' + url);

I would however recommend putting them on two lines, like this:

var url = document.links.mylink.href; 
document.write('The URL is ' + url);

..and using var to declare url as a variable, good practice
