Doctype And Older Versions Of HTML

Can anyone explain why this works?

I used an online service to create a slideshow for my site. It worked on my Vista box, but on my XP box it only worked in Chrome, not in IE8. So I assumed it was in HTML5.

Today I was playing with the code with a view to (a) using it on other sites, and (b) making a version that worked on all browsers. I discovered the slider was entirely Javascript, so should work on IE8. Buggering about with it, I found that adding a doctype tag (doctype html) made it work. Why should this be? Why when everything else appears to work 100% OK without a declaration of doctype, should one Javascript piece of code require a doctype declaration?
