2,599 PointsDifferent code syntax still works. Why?
I wrote my code differently and it worked. Is there a reason to do it his way vs the way I did it (ie. faster, efficient, etc)?
Here's my code:
var adjective = prompt("Give an adjective");
var verb = prompt("Give a verb");
var noun = prompt("Give a noun");
alert("You said " + adjective +"/ " + noun +"/ "+ verb);
document.write("There once was a " + adjective + " programmer who wanted to use " + verb + " javascript to " + noun + " save the world.");

I'd say it's a little down to personal preference but ideally you'd want to make the code easy to understand for any other developers working on your project. Dave's example is simply demonstrating building up the string using concatenation to test it and display it.
You could potentially have a large amount of variables and so writing them all in a line might require side scrolling. Breaking it down as Dave has could be considered clearer on this occasion. This is just an example of why it might be used.
Hope that helps :)
