in .NET you have <%= or <%: in PHP it's echo, but does JavaScript have a shorthand for document.write()?

Thanks

No, it doesn't.

You can always:

function x (foo) { document.write(foo); } 
/* Where x is an unhelpfully short and uninformative function name */

Generally speaking, document.write should be avoided anyway. It is only useful during initial document generation and does nothing to handle special characters.

Yes, more than one.

But "with" is considered harmful because if you make mistake to call a property that is not set you can change the value of another property or create a new global variable with that property ( more info here )

example

var d = document;
d.write('text');

with (document){
    write('text');
}

The innerHTML property is a useful one for HTML elements. You can use that rather than document.write.

<p id="paragraph1"></p>

<script type="text/javascript">
var elem = document.getElementById("paragraph1");
elem.innerHTML = "This is my paragraph.";
</script>

That allows you to have a lot more control over what you are outputting to the page. You can make that a bit easier to digest by wrapping it in a function - once you've declared the function once, you can reuse it as many times as you like:

<script type="text/javascript">
function wr(a,b) {
var elem = document.getElementById(a);
elem.innerHTML = b;
}
</script>

Very simple example, should be refined etc.
