// because of hoisting, variables are typically declared at the top of the "scope"
// var a = 1;
// var b;
// var h = "hello";

// you can declare multiple variables at once
// var a = 1, b, h = "hello";

// make sure the file is working
// console.log('hello');

Rapid Prototyping with Rails

At Wyncode we turn people into full-stack web developers in 10 weeks. So we've learned a few tricks to get from 0 to webapp quickly.

Install Ruby and Rails

• Ruby
• Rails

Generate the app skeleton

eddroid

# title
puts "Chapter 1"

# line 1
puts "It was the best of times"

# rest of the text
puts "It was the wrost of times"

eddroid

// Paste into the JavaScript console.
//
// Add "javascript:" to the front if you want to bookmark it

// South Florida Business Journal
$('.content--embargoed').attr('style', 'display: block !important; opacity: 1');$('.paywall--premium').remove();$('.paywall--free').remove();$('.paywall--free').hide();$('.content__segment').show();

// Miami Herald
$("#ppUI").hide() && $("#pressplusOverlay").hide()

eddroid

class Node
	def initialize(xml_str)
		@name = @attributes = @content = ''
		parse(xml_str)
		p @name, @attributes, @content
	end
  
	def parse(xml_str)
		# state indicators
		inside_tag = inside_tag_name = inside_tag_attributes = false

Puma Hunter

Hunts down and kills loose Puma Rails server processes.

Build

You only need to run this once.

# Terminal

eddroid

require 'rspec/autorun'

# A Set is an Array that is automatically de-duplicated (uniq'd)
require 'set'


####
## Coordinate
##
## an x,y coordinate pair

eddroid

module AlphabetTesters
  # self methods
  #   activated on require
  #   must be called with namespace
  #     e.g. AlphabetTesters.a?
  def self.a?(letter)
    letter.downcase == "a"
  end

  def self.b?(letter)

eddroid

# display a line on the screen
#
# refactoring to 
# - remove some Ruby jargon by defining a 
#   domain-specific-language (DSL)
# - remove some repetitive (copy-pasted) code
# - have a single place to change the line width
def put_a_line
  puts "*" * 50
end

Scope

Think of a telescope. As it extends right, it gets smaller.
