instance method
blank?
Ruby on Rails edge
Signature
blank?()An object is blank if it’s false, empty, or a whitespace string.
For example, `nil`, '', ' ', [], {}, and `false` are all blank.
This simplifies
```ruby
!address || address.empty?
```
to
```ruby
address.blank?
```
@return [true, false]: () -> bool
