Grep vs Filter in jQuery?

Question

I was wondering about the differences between Grep and Filter :

Filter :

Reduce the set of matched elements to those that match the selector

Answer 1

They both function in similar ways however they differ in their usages.

The filter function is intended to be used with html elements, and that is why it is a chainable function that returns a jQuery object and it accepts filters like ":even", ":odd" or ":visible" etc. You can't do that with the grep function, which is intended to be a utility function for arrays.
