Documentation : Getting Started "case cond and if"

[anishcr]

In https://elixir-lang.org/getting-started/case-cond-and-if.html

It is mentioned - "If any variable is declared or changed inside if, case, and friends, the declaration and change will only be visible inside the construct."

I did not understand "and friends". Is that a typo or there is something called "friends"?
