Speaking of `document.head`, I think Mootools does exactly that.
Good thinking. I took a look at some JavaScript Libraries /
Frameworks. Here are some quick counts of how many times I could
see that they use the "getElementsByTagName" method of getting the
"head" element:
- MooTools 1.2.3 has: 2
- jQuery 1.3.2 has: 2
- Ext 3.0.0 has: 5
- YUI 3.0.0b1 has: >10
- Prototype 1.6.1, MochiKit 1.4.2, Dojo 1.3.2 have: 0
There are none in Prototype.js simply because it is a rather small and
low level library (I'm one of its core developers, btw). Libraries
that use, say, "global eval" abstraction and/or dependency management
(for scripts and styles) such as YUI obviously use HEAD more often
(which your numbers confirm).
