Subject: [ruby-core:106074] [Ruby master Feature#18332] a ? b

Issue #18332 has been updated by shan (Shannon Skipper).


Control flow operators are another option that reverses the direction.

``` ruby
true and 'font-bold'
#=> "font-bold"

'font-bold' if true
#=> "font-bold"

nil and 'font-bold'
#=> nil

'font-bold' if nil
#=> nil
```

Feature #18332: a ? b

It would be a shortcut for `a ? b : nil`:

e.g.

```
"#{current_path == "/" ? "font-bold"}"
"#{user.admin? ? "text-red-600"}"
```

Doing `a && b` returns `false` which converted to a string gives `"false"`.

When `nil` converts to a string it gives `""`.

I would use it mostly in string interpolations.
