JS Script Declaration Syntax

Question

I'm not sure what is the difference between opening a JS script with

<SCRIPT language='JavaScript'>

or using:

<SCRIPT type="text/JavaScript">

If JavaScript is always quoted (either with "" or c ''), or is that not important?

Thanks for any clarification on this topic!

Change . The opinion is made, it seems, here, my bad. Single quotes are technically legal, but, in my experience, they tend to lead to more problems than double quotes (they often occur among attribute values ​​among other things), so I always recommend sticking to the latter. Your mileage may vary, though!
