When looking at RuboCop's code, I noticed a big number of frozen arrays being used only to later call include? on them. This is O(n) instead of O(1).
Trying to convert them to Sets causes major compatibility issues, as well as very frustrating situations (See set.join and array + set) and where the fact that they are now Sets makes them much less efficient (See array & set).
Here are the improvements that would improve Sets:
| # gem install 'benchmark-ips' | |
| require 'benchmark/ips' | |
| long = ' ' * 1_000_000 + 'x' | |
| REGEXP = /\A[[:space:]]*\z/ | |
| [' ', 'hello', long].each do |str| | |
| Benchmark.ips do |x| | |
| x.report('with_regexp') { REGEXP.match? str } |
