RubyConf 2022: Ruby Lambdas by Keith Bennett

Object Oriented Design is powerful for organizing software behavior, but without the benefit of lambdas' code-as-data flexibility, it often fails to reduce solutions to their simplest form. Although Ruby's Enumerable functionality is widely appreciated, its lambdas generally are not. This presentation introduces the developer to lambdas, and shows how they can be used to write software that is cleaner, simpler, and more flexible. We'll go through lots of code fragments, exploring diverse ways of exploiting their power and identifying reusable functional design patterns along the way.
