Best practice for using DOM Level 0 in modern JavaScript applications

Question

Is there an agreed set of \"best practices\" for use of the DOM Level 0 collections in modern JavaScript applications? (document.forms, document.images

Answer 1

For better or for worse, I use pure DOM level 0 features mainly for debugging. It is sometimes faster to inspect document.forms[0].elements for inputs.

I also use such features when I'm inspecting some page which use some esoteric (or simply unknown to me) framework. I have no time to dig into those abstractions and just inspecting collections directly.

I do believe you'd better know all this DOM zero arsenal, but it's even better if you know about all this modern pure DOM don't-know-which-level-it-is-exaclty level APIs. ClassList collections are nice, for example. I mean, if you are using a framework, you should always know, why do you exactly need it.
