In Ruby 2.3 or later, `String#+@` is available and `+@` is faster than `dup`. ```ruby # frozen_string_literal: true require "bundler/inline" gemfile(true) do source "https://rubygems.org" gem "benchmark-ips" end Benchmark.ips do |x| x.report('+@') { +"" } x.report('dup') { "".dup } x.compare! end ``` ``` $ ruby -v benchmark.rb ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux] Warming up -------------------------------------- +@ 282.289k i/100ms dup 187.638k i/100ms Calculating ------------------------------------- +@ 6.775M (± 3.6%) i/s - 33.875M in 5.006253s dup 3.320M (± 2.2%) i/s - 16.700M in 5.032125s Comparison: +@: 6775299.3 i/s dup: 3320400.7 i/s - 2.04x slower ```
