What do JavaScript validators mean by columns?

For example, I got this warning: Expected 'this' at column 5, not column 3.

What is that referring to?

Normally it has to do with the characters on the line:

// X <-- this "X" is in column 4
//       Y <-- this "Y" is in column 10

But since spacing is not normally important in JavaScript, this message seems very peculiar. It would help to see the actual code involved. If possible, make a snapshot of your workspace and post the link to it here.

I was looking at different validators yesterday and I don't remember which one mentioned columns. Probably not a great one judging from your answer. I've settled on JSHint which seems to be good. Better than JSLint which is just confusing.
