make example suitable for teenagers/children!?

Maybe that's quite a conservative attempt.
The [*Check for spam* chapter of *Strings*](https://javascript.info/string#check-for-spam) has an example that uses *viagra* and *XXX*.

Considering that nowadays also many young people learn coding on JavvaScript.info I'd personally consider it more suitable (aka. inclusive) for all ages to simple use a different topic that's not so adult-ish.

What do you think?

Start with the linked Check for spam section in the Strings chapter and review the current example. Choose a non-adult topic that preserves the example's purpose, update the example, and confirm the chapter remains clear for younger readers.
