Ruby 2.6 added block argument processing to `Enumerable#to_h`. https://bugs.ruby-lang.org/issues/15143 Rails 7 requires Ruby 2.7.0 or higher, so the new feature can use it. `Style/MapToHash` cop will detect it. And this cop in the `Style` department, but this seems to improve performance as follows: ```ruby # map_to_hash.rb require 'benchmark/ips' ARRAY = (1..100).to_a HASH = {foo: 1, bar: 2} Benchmark.ips do |x| x.report('array.map.to_h') { ARRAY.map { |v| [v, v * 2] }.to_h } x.report('array.to_h') { ARRAY.to_h { |v| [v, v * 2] } } x.compare! end Benchmark.ips do |x| x.report('hash.map.to_h') { HASH.map { |k, v| [k.to_s, v * 2] }.to_h } x.report('hash.to_h') { HASH.to_h { |k, v| [k.to_s, v * 2] } } x.compare! end ``` ```console % ruby map_to_hash.rb Warming up -------------------------------------- array.map.to_h 9.063k i/100ms array.to_h 9.609k i/100ms Calculating ------------------------------------- array.map.to_h 89.063k (± 3.9%) i/s - 453.150k in 5.096572s array.to_h 96.449k (± 1.7%) i/s - 490.059k in 5.082529s Comparison: array.to_h: 96448.7 i/s array.map.to_h: 89063.4 i/s - 1.08x (± 0.00) slower Warming up -------------------------------------- hash.map.to_h 106.284k i/100ms hash.to_h 149.354k i/100ms Calculating ------------------------------------- hash.map.to_h 1.102M (± 2.2%) i/s - 5.527M in 5.019657s hash.to_h 1.490M (± 0.9%) i/s - 7.468M in 5.013264s Comparison: hash.to_h: 1489707.0 i/s hash.map.to_h: 1101561.5 i/s - 1.35x (± 0.00) slower ``` `Style/MapToHash` cop ... https://docs.rubocop.org/rubocop/1.25/cops_style.html#stylemaptohash
