True and False vs. "Truthy" and "Falsey" (or "Falsy") in Ruby, Python, and JavaScript
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.
