  ### Different from airbnb config

  ### Styling ###

  # better to ignore comments and others
  max-len: off

  # I prefer new line before error
  # http://eslint.org/docs/rules/newline-before-return
  newline-before-return: error # airbnb default: off

  # I prefer double quotes
  # http://eslint.org/docs/rules/quotes
  quotes: [error, double] # airbnb default: ['error', 'single', { avoidEscape: true }]

  # enforce no padding inside curly braces
  #http://eslint.org/docs/rules/object-curly-spacing
  object-curly-spacing: [error, never]

  ### Variables ###

  # Functions and classes can be used before declaration
  # http://eslint.org/docs/rules/no-use-before-define
  no-use-before-define: # airbnb default: error
    - error
    -
      functions: false
      classes: false

  ### ES6 ###
  # enforce usage of spacing in template strings
  # http://eslint.org/docs/rules/template-curly-spacing
  template-curly-spacing: [error, never] # airbnb default: error

  ### Best practices ###
  # require or disallow Yoda conditions
  yoda: [error, never, { exceptRange: true }]

  # I prefer culry braces all the time
  curly: [error, all] # airbnb default: [error, multi-line]
