jQuery `children` versus ` find`

Question

HTML

<table id='t'>
  <tr>
    <td id='foo' class='a b c'>blah</td>
    <td id='bar' class='a c'>bloo</td>
    <td id='zip' class='a b c'>blop</td>
 </tr>
</table>

Using jQuery, why does the following children call return 0

$('#t').children('tr').length

but find returns 1?

$('#t').find('tr').length

Answer 1

Because browsers automatically add a tbody element if you don't.

console.log($('#t').children().get(0).tagName);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id='t'>
  <tr>
    <td id='foo' class='a b c'>blah</td>
    <td id='bar' class='a c'>bloo</td>
    <td id='zip' class='a b c'>blop</td>
 </tr>
</table>
