I like when strings look pretty. I especially like it when strings detailing amounts of items can discern whether or not to use the plural form of the noun, such as goose vs geese, or die vs dice.

Most people have strings set up that look something like:
"You have [n] octopi in your bag."

Which, to be fair, 99% of the time will be perfectly okay, but what about that handful of times where n is a 1? "You have 1 octopi in your bag." sounds really weird, so let me show you a very simple way to conjugate plurals dynamically without adding any more lines of code.

This trick uses the inline conditional statement format [condition ? true : false]. A lot of people already know this, but there are likely others out there who don't who might find this interesting injection enlightening and useful.

Now, let's put that into the previous string. These conditionals can fall between braces like any normal variables and expressions.

Now the string becomes: "You have [n] [n == 1 ? "octopus" : "octopi"] in your bag."

And ta-da! Literally the simplest way to make text output more dynamic. I know a short snippet tutorial like this is intended for beginners, but still, as long as someone learns something.
