Steps to reproduce the problem
file.rb:
array_of_hashes
.map(&:to_a)
.flatten(1)
.each_with_object({}) { |(k, v), h| (h[k] ||= []) << v }rubocop --autocorrect-all --only Performance/FlatMap file.rb
RuboCop version
Include the output of rubocop -V or bundle exec rubocop -V if using Bundler. Here's an example:
You can see extension cop versions (e.g. rubocop-performance, rubocop-rails, and others) output by rubocop -V,
include them as well. Here's an example:
$ [bundle exec] rubocop -V
