I've just started using jquery and I'm really enjoying using selectors. It occurs to me that the idiom would be a very nice way to traverse object trees (e.g., JSON query results). For example, if I have an object like this: var obj = { 'foo': 1, 'bar': 2, 'child': { 'baz': [3, 4, 5] } }; I would love to be able ...

Sometimes it is useful to have an empty jQuery object, to be used either as a default value or as an initial value, when constructing a collection of items. For an example, see here. One way to do it would be to use a selector which is unlikely to match anything, like $('skdhjfksjdhfksjhdf'), but this is obviously inelegant. How can I...

I want to try and standardise on one best-practice approach, but before I do that I want to ensure that I pick the most efficient. Does anyone have links to good articles (such as this one) that make comparisons between different types of sele...
I'm not sure whether to use :first or :eq(0) in a selector. I'm pretty sure that they'll always return the same object, but is one speedier than the other?
