• Based on tuples from set theory.
• They are one of the oldest, most commonly used data structures.

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

This is in response to your question about initializing a new instance of a class, and correspondingly passing in parameters that are initialized with the class. Let's take an example below:

class Person
  def initialize(name)
    @name = name
  end

Form_for

• Most magical form helper in rails
• form_for is a ruby method into which a ruby object is passed
• form_for yields a form builder object (typically f)
• methods to create form controls are called on f, the form builder element
• when the object is passed as a form_for parameter, it creates corresponding inputs with each of the attributes
  • if i had form_for(@cat), then the form field params would look like cat[name], cat[color], etc
• in keeping with Rails convention regarding RESTful routes, there should be a resource declared for each model object (eg, resources :cats)
