Now the _relevant_ part is that
this entire chunk of code is an expression
it evaluates to a single value which means it's "_portable_"
you can pick it up and just drop it somewhere else
this entire chunk of code is an expression;
it evaluates to a single value which means it's "_portable_".
You can pick it up and just drop it somewhere else
and just say "`foo` equals `if quantity == 1 then singular else plural`..."
you can do that anywhere you would have any single value
you can just drop in this entire `if` expression
You can do that anywhere you would have any single value.
You can just drop in this entire `if` expression,
perhaps with parentheses around it to disambiguate.
And it's exactly the same thing with the ternary
and so you need this both `if` and `else`

So we're like:
`pluralize "leaf" "leaves" 1`

It gives us "leaves".
Great! that's what we _expect_!
Any number over 1 should give us the `plural` form.
And then let's say,
when we implemented this we _accidentally_ made a typo here:
Instead of `singular` we said `singula` ...
Ok, so, as we can see, this code _still works_!
