I'm not following you. I'll need some more info.

Java or Javascript... 2 different things.
Also...
Containter or Container?

Or, if you don't want a pop-up, which is blocked by a lot of browsers anyway:
<script>
document.write('Hello, World!')
</script>

Sorry I meant javascript, I'm just trying to be able to preview code like before I actually publish it to the internet.

If you were to build a code that actually did say "hello world" really fast and wanted to preview it in your browser at work lets say and you could just click "live preview" and it would show up in your browser as if you had published it, without publishing it.

EDIT: Or just use the CC HTML Editor. You can preview everything there...

Exactly what I wanted to say too. Js is client based, not like php which is server based, and you can bang the js onto a website and preview it locally.

Ok then I need to get a new browser .. i'm linking my sources correctly as far as I know, and have just one string which is hello world, and when I go to preview it in CC Html or anything else I get a grey screen. Google Chrome must not support pop up javascript then?

The problem is not the browser, nor is it the HTML Editor!

This line:
ContainterName.FunctionName(a,b,c,d)
Gets these warnings (in JSbin):
ContainterName is not defined, missing semi-colon
Are you sure it should be containter rather than container?
Until you find/correct all the errors, it won't matter what browser you use. It won't preview unless everything is correct.
Have you tried running the simpler versions Eric and Inger suggested? Try something simple first to test it out.
<script src="js/01-function.js" /> might change this to:
<script src="js/01-function.js" ></script>
Good overview here (JS in head, JS in body, linking to JS files):
