ForEachTiddler: show Tiddlers without matching tag

This is probably a simple Javascript question:

Using the ForEachTiddler plugin, if I wanted to list all the
tiddlers
that have a tag, for example, Work, I would use

'tiddler.tags.contains("Work")' with the where
clause

What if I wanted to see exactly the opposite, i.e. all
tiddlers that
do NOT contain the Work tag?

Thank you

In javascript, preceding a boolean (true/false value) with
a
"!" (exclamation point) inverts the value,
changing "true" into
"false" (or "false" into
"true").  Thus, for your use-case, simply add
a ! immediate preceding "tiddler...", like this:

'!tiddler.tags.contains("Work")'
