99 Bottles Chapter 4: Practicing Horizontal Refactoring

Github commits: https://github.com/nt591/99bottles-ch4/commits/master

Replacing Difference With Sameness

The first goal for horizontal refactoring is to identify the MOST ALIKE pieces of code (aka the smallest amount of difference to change). In this case, look at the case for 1 and else

What are the differences? First number (1 vs number-1, bottles vs bottles/container(), take it down vs take one down.

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

	class Board
	attr_reader :board
	PADDING_VAL = 10000

	def initialize
	# filler value so i dont need to check for nil
	@board = Array.new(9) {\|i\| PADDING_VAL + i}
	end

	def render_cell(cell)

	class EventEmitter {
	constructor() {
	this.events = {}
	}

	// helper
	hasEvent(event) {
	return this.events.hasOwnProperty(event)
	}
