How to get a value of a CheckBox from td (table), JavaScript?

I have a table with text data but in one cell I have a checkbox. I can extract data from td, but I can't figure out how to extract the checkbox value

Here's what I've tried (see attached picture!)

$('#tableData tbody tr:eq('+row+')').find('td:eq(8)').eq(0).value
