Variables and Operators lesson : Fix misleading Filename

[xerxes324]

Changed from "no name .js " to " noname.js " for better clarity, as the former might confuse people into creating a literally empty .js file.

Because

" no name .js " can be confusing for people as it might lead them to think its an empty .js file which can cause an error. Changing it to noname.js can probably help avoid the confusion.

[ At the very least, it can be changed from the existing " no name .js " to " noname .js ". ]

This PR

• no name .js changed to noname.js in the variables_and_operators section of the Foundations Course.

Closes #XXXXX

I see the confusion, but what it is saying here is that there is no name. The file is just .js. I am open to clarifying the sentence.

Suggested change

	We named our file `javascript.js` but we could have chosen any name like `my-script.js` or even `noname.js`. What is really important is the `.js` extension.

Well, this was the source of the confusion. someone tried it and it gave them an error ( possibly because of the naming? )
I'm not sure, please do clarify.

It seems if the script src leads to a file name that begins with a dot, the browser interprets the MIME type as text/html even if it's explicitly set to text/javascript (which would otherwise be implicit). Tested this with various file names inc. .n.js and n.js, both with and without the leading ./
.js as a plain file name does work when running via node e.g. node .js but in this example, it'll be better to use an example other than nameless .js

The .js also isn't the important part either. Naming and src-ing the file javascript.rb will work just fine (with JS code of course), as long as the path indicates a file (just javascript no extension will end up with a MIME type of text/html, even if explicitly set in the script tag.

I have tried it, and .js as a plain file name also does work in browser console and also with node .js as clarified by @MaoShizhong. Thankyou so much for clarification.
