A design pattern in functional programming that allows for a generic type of computations to be performed in a specific context (like handling nulls, combining computations, or dealing with side effects).

"Monads provide a way to wrap and chain operations on values while abstracting away details such as error handling or asynchronous computations."

A programming concept where a variable in a nested scope has the same name as a variable in an outer scope, effectively hiding the outer variable within the inner scope.

"The team added Webpacker to their Rails project to take advantage of modern JavaScript features and tools."

In programming, the process of breaking down a complex problem or function into smaller, more manageable parts, often to improve readability or reusability.
