Benchmark: interpolation vs concatenation in Ruby
require 'benchmark'
count = 1_000_000
Benchmark.benchmark do |bm|
bm.report("concat") { count.times { 11.to_s + '/' + 12.to_s } }
bm.report("interp") { count.times { "#{11}/#{12}" } }

Last active December 10, 2015 18:58
Example uses of Object#tap that I really like
# Logging some action in the console or log file
# Prevents lots of references to a variable
# Maybe not the best example, but potentially cleaner than the alternative

@account = account
end
def method_missing(method_name, *args, &blk)
if account.respond_to?(method_name)
account_method_result(method_name, *args, &blk)
