Filter and Find both are nearly similar but there is one difference.
Filter: Looks though the elements at all levels(based on the selector we give), whether it's a child of some other element or it is itself a parent.
Find: This looks only at the child level.
Example: This will help you understand the difference. And you will realize, how important both are in their own way.
1. Find: This will only select the <div id="Fruits"> inside the <div id="Category">.$('div').find('#Fruits')$('div').filter('#Fruits')
HTML :-
<html><body>
<div id="Fruits">
Fruits
<div id="Apple">Apple</div>
<div id="Banana">Banana</div>
</div>
<div id="Category">
Category
<div id="Fruits">Fruits</div>
<div id="Animals">Animals</div>
</div> </body></html>
