    true and false vs. "truthy" and "falsey" (or "falsy") in Ruby, Python, and JavaScript

Many programming languages, including Ruby, have native boolean (true and false) data types.  In Ruby they're called true and false.  In Python, for example, they're written as True and False.  But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).
This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too.  The idea is much more general than any of these specific languages, though.  It's really a question of how the people designing a programming language wants booleans and conditionals to work.

                15 Questions to Ask During a Ruby Interview
              
          
    Originally published in June 2008
When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first.  In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written.  And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
What to expect

Candidates will typically give you a range of responses based on their experience and personality.  So it's up to you to decide the correctness of their answer.
