Learn the core bits every Ruby programmer should know. This Ruby tutorial builds upon the basics to keep enhancing your Ruby knowledge.

LEVEL 1 - EXPRESSIONS
An overview of best practices for writing expressions in Ruby
LEVEL 2 - METHODS & CLASSES
passing optional arguments, raising exceptions, using begin/rescue/end, attr_accessor vs. attr_reader
LEVEL 3 - CLASSES
Encapsulation, instance & private methods, inheritance, and refactoring
LEVEL 4 - ACTIVESUPPORT
Helpers that are built on top of the Ruby Language (arrays, dates, hashes, numbers, and strings
LEVEL 5 - MODULES
Namespacing methods, Mixins vs. class inheritance, method hooks, ActiveSupport::Concern
LEVEL 6 - BLOCKS
Iterating and yielding, passing arguments, returning variables, Enumerable, and refactoring
