Description: A Proc in Ruby is a block of encapsulated code that can be stored in a variable and executed later. Unlike code blocks that are passed directly to methods, Procs allow for greater flexibility by being assignable to variables, passed as arguments, and called in different contexts. A Proc can accept parameters and return values, making it a powerful tool for functional programming within Ruby. Additionally, Procs maintain the context of the variables at the time they were created, meaning they can access local variables from their original environment even after that environment has changed. This feature is known as ‘closure’, and it is fundamental to understanding how Procs work in Ruby. In summary, Procs are a way to encapsulate logic that can be reused and manipulated efficiently, contributing to the modularity and clarity of code in many programming applications.
