PROJECT LEARNING GOALS

Rating	Content	Description
	Variables	Variable names are logical, clear, and in snake case. Variables are not needlessly assigned or reassigned. Instance variables are used for visibility within all methods in the class. Local variables are used for visibility only to a single code block or method. (variable examples).
	Loops	Loops control the flow of the code, keeping the user on track, and continuing the program until an appropriate end point.
	Data Types	Hashes, arrays, strings, symbols, numbers, and booleans used appropriately. (data type examples)
	Conditionals & Operators	Logical and mathematical operators guide program flow efficiently and properly deal with edge cases (operator/conditional examples).
	Methods	Methods are designed and implemented with a single purpose. Methods are logically named in snake case.
	Classes	Classes are used to represent a single object, and contain all of the functionality and information associated with that object.

Examples

Variables

# Good:
post_height = 7.0
user_name = gets.chomp

class Item
  def initialize(item_name)
    @item_name = item_name
  end
end

# Bad:
p = 7
ph = '7.0'
postHeight = 77

class Item
  @item_name = # Incorrect usage outside of a method in class scope
end

Conditionals & Operators

x = 2

# Good:
if x < 2
  result = "x is less than 2"
elsif x > 2
  result = "x is greater than 2"
else
  result = "x is exactly 2"
end

puts result

# Bad:
if x < 2
  result = "x is less than 2"
elsif x > 2
  result = "x is greater than 2"
end

puts result

Data Types

# Good:
name = "Bobbina"
honorific = "Ms. #{name}"

# Bad:
num = '2'
total = 1 + num.to_i

CODE QUALITY

Rating	Skill	Description
	Correctness	Code runs without errors or bugs. Edge cases are tested for and handled appropriately.
	Readability	Formatting is consistent. Naming conventions are followed. Use of white space and tabs are consistent. Code is concise. Each group of statements creates a complete thought and those thoughts are separated by blank lines. Variable, method and class names are meaningful.
	Structure	Methods perform one, and only one, function. Blocks of code that are run multiple times are not cut-and-pasted, but instead are written as loops and functions. Variables are not duplicated unnecessarily.
	Efficiency	There is no unused code included.
	Comments	Comments accurately describe code logic and are placed before or on the line they describe. Comments are either: information that can’t be expressed in code, intent comments, or summary comments.
