I saw the tutorial below on w3 schools website but I don't get the part where it says "Browsers that do not support JavaScript will display JavaScript as page content?" What does that mean I do not understand.

Browsers that do not support JavaScript will display JavaScript as page content.
To prevent them from doing this, and as a part of the JavaScript standard, the HTML comment tag can be used to "hide" the JavaScript. Just add an HTML comment tag  (end of comment) after the last JavaScript statement.
<html>
<body>
<script type="text/javascript">

</script>
</body>
</html> The two forward slashes at the end of comment line (//) is the JavaScript comment symbol. This prevents JavaScript from executing the --> tag.

Hi

It simply means that if someone surfing the web has Javascript turned off on their web browser then the browser will display the Javascript code on the web page.

Putting the code between the HTML comment tags  hides the script so if Javascript is turned of the browser will ignor it and not display it on the web page. and the // stops JavaScript from trying to execute the --> as code. so it would look like

hi thanks for the reply. So what would be the purpose of having that script inside the <-- Javascript //--> if people do not want it to show why don't they just get rid of it you know? And not even put the <-- Javascript //-->

browsers that are javascript enabled will run the script because the will ignore the comments inside the <script...> tags.

If you took it out of the page no user agents at all could possibly run the script.
