Hey, let’s talk about memoization.

I would like to address one of our coding habits. I notice that we have a tendency to overuse memoization. I would like to point out that memoization is a double edge sword and does not always yield expected results.

Here is an example. I pulled it from recent code I saw:

require 'benchmark'
require 'active_support/all'
EDUCATION_DURATION_ESTIMATE = 10.years

First install Brew on your MAC

Setup Brew: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew tap homebrew/dupes
brew tap homebrew/php
Install PHP 7.1.+ brew install php71 --with-postgresql
Install mcrypt: brew install mcrypt php71-mcrypt
Finally, install composer: brew install composer

	// Let's say we have a product that validates emails.
	// Person visits our websites gives us a list of emails and we validate that those emails are real.

	// Our value is "Great customer experience".
	// We have two engineers in our company and they both inline with our values.
	// However they disagree on qualities that our code should have.
	// Person "A" believes that we should optimize for maintenability.
	// Person "B" is sure that we should optimize for change.
	// They both send to implement an email validator.

	module ShitGrouper
	def self.group(array)
	array.group_by(&:year)
	end

	def self.ungroup(hash)
	hash.values.flatten
	end
	end

	class Rule {
	private operations: Array<any>;

	constructor() {
	this.operations = [];
	}

	filter(options): Rule {
	this.operations.push({ action: 'filter', options });
	return this;

	class Point
	attr_reader :x, :y

	def initialize(x, y)
	@x = x
	@y = y
	freeze
	end

	def move!(x_offset, y_offset)
