jQuery Link Codes: Workspace Vs jQuery Download

I notice that the jQuery link code in Workspace seems different to the one we were directed to in the jQuery website (CDN). The one in worskspace has 'type" plus 'charset' is I have copied and pasted it here: 

<script src="http://code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>.

But if you look at the one from 'jQuery's CDN provided by MaxCDN' it does not have the 'type' and 'charset' like here: 

<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>

So what is the difference and why are we being told to use CDN and Treehouse goes on to use something else in their examples without any warning or telling us why?

Looking at the MDN page on <script> element it's related to HTML 4 vs 5. HTML 5 may not be in use everywhere, yet, so the HTML 4 syntax is safer.

<!-- HTML4 and (x)HTML -->
<script type="text/javascript" src="javascript.js"></script>

<!-- HTML5 -->
<script src="javascript.js"></script>

The use of the charset is to stipulate the encode for the external (in this case the jquery.js) file. This, again, is a safety usage for cases where the main HTML page is using a different encoding than the "utf-8" contained in the jquery.js file.

i would recommend the teamtreehouse version. its "safer" because you tell the browser how to interpret the src-file. this would be important if you use a different charset for your code than the .js file is :)

because most of the time it works fine without adding the attributes you mentioned. we are all a bit lazy :P i have to admit it, i also use the shorter version ;(
