Q:

jshint, eqnull, Use '===' to compare with 'undefined'

I apologize ahead of time, I am clearly utterly incapable of understanding how to configure jshint.
I have this line of code
if ( data == undefined || (typeof data === 'object' && data.length === 0) ) {
...

jshint is underlining the first == and saying

Use '===' to compare with 'undefined'.

I added /* jshint eqnull:true */. I thought this is what the option does. I even see an example here (search for eqnull).
What am I missing?

A:

Use this option for the same
"-W041": false
