Lamba

A lambda (λ) is a symbol used in various fields with different meanings. In mathematics and computer science, particularly in functional programming, lambda refers to anonymous functions—small, unnamed blocks of code that can be defined and used instantly without being formally declared. These functions can take inputs and produce outputs immediately, making code more flexible and concise. Think of a lambda as a quick, on-the-spot recipe or instruction, used when you need a simple function without creating a formal, reusable formal definition.
