>If you only ever coded in a language that doesn't even offer you the ability to tinker with some concepts, you can't be familiar with those. Reading one article about it without ever touching code, is not being familiar with a programming concept.

I disagree, you're familiar by definition.

You're just not experienced and may be not aware of pros and cons unless the article/book/w.e showed them.

Whether experience is important is up to the thing you're talking about.

For example: stealing Result<T> from other language to replace exceptions in your language doesn't require you to use Result<T> impl. in other lang.
