# ### Examples
|
|
#
|
|
# ```
|
|
# [1, "", nil, 2, " ", [], {}, false, true].compact_blank
|
|
# # => [1, 2, true]
|
|
# ```
|
|
#
|
|
# ```ruby
|
|
# Set.new([nil, "", 1, false]).compact_blank
|
|
# # => [1]
|
|
# ```
|
|
#
|
|
# When called on a {Hash}, returns a new {Hash} without the blank values.
|
|
#
|
|
# ```ruby
|
|
# { a: "", b: 1, c: nil, d: [], e: false, f: true }.compact_blank
|
|
# # => { b: 1, f: true }
|
|
# ```
