Which one is more efficient?

benchmarking.rb

require 'benchmark'

puts Benchmark.measure do
  1000.times{method1(array)}
end
# ...
#  0.020000   0.010000   0.030000 (  0.027314)
puts Benchmark.measure do
  1000.times{method2(array)}
end
# ...
#  0.010000   0.010000   0.020000 (  0.026339)

two_options.rb

array = ['banana', 'cat', 'pineapple', 'egg', 'fridge', 'smudge', 'panda']

# More efficient?
def method1(array)
  array.reject{|thing| thing.include?('a')}.each do |thing|
    puts thing.reverse
  end 
end

# Or is this better?
def method2(array)
  array.each do |thing|
    next if thing.include?('a')
    puts thing.reverse 
  end
end
