Syntax question

Hi, I was just looking at the tutorialssection when I came across this:

[AS]import flash.filters.GlowFilter;
var gf:GlowFilter = new GlowFilter(0x356D83, 100, 3, 3, 5, 3, false, false);
kText.filters = [gf];[/AS]

I understand that, when applying filters, you have to work with arrays. But I’ve never seen the [value] syntax before, as shown above. Is it a short version of putting all of your items in an array?
