Learning Ruby: naming conventions

Ruby has specific naming conventions that make it easier to write and read code. I would like to summarize them here in a cheatsheet format that is easier to refer to.

snake_case:

• files
• variables
• methods

#files
my_first_ruby_file.rb

#variables
programming_language = "Ruby"

#methods
def make_an_example
  #do stuff
end

UPPERCASE:

• constant variables

Constant variables represent values that will not change during your Ruby program.

ID = AB123456
FAVORITE_FOOD = "Pizza"

CamelCase:

• classes

class Person
end

class Movie
end

Additional note

When working with do/end blocks, it is preferable to use { } when the code can fit in a single line

characters = ["Eleven", "Mike", "Dustin", "Lucas", "Will"]
characters.each do |character|
  puts character
end

characters.each { |character| puts character }
