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

Both find() and children() methods are used to filter the child of the matched elements, except the former is travels any level down, the latter is travels a single level down.

To simplify:

1. find() – search through the matched elements’ child, grandchild, great-grandchild... all levels down.
2. children() – search through the matched elements’ child only (single level down).
