What is fastest children() or find() in jQuery?

Question

To select a child node in jQuery one can use children() but also find().

For example:

$(this).children(\'.foo\');

gives the same result

Answer 1

None of the other answers dealt with the case of using .children() or .find(">") to only search for immediate children of a parent element. So, I created a jsPerf test to find out, using three different ways to distinguish children.

As it happens, even when using the extra ">" selector, .find() is still a lot faster than .children(); on my system, 10x so.

So, from my perspective, there does not appear to be much reason to use the filtering mechanism of .children() at all.
