Browser Support

<noscript> Yes Yes Yes Yes Yes Yes

Tip: If the browser supports scripting, it will not display the text in the noscript element.

Note: Unrecognized <script> The tab browser displays the contents of the tab on the page. To prevent browsers from doing this, you should hide the script in the comments tab. Old-fashioned(Unrecognized <script>(Tag) browsers ignore comments, so they do n’t write the content of the tags to the page, and modern browsers know how to execute these scripts, even if they are enclosed in comment tags!

function displayMsg() {
    alert("Hello World!")
