Lambdaketjut

Lambdaketjut, often translated as "lambda chains," are a concept primarily discussed within the context of functional programming languages, particularly Lisp dialects like Scheme and Clojure. They refer to a pattern where a series of anonymous functions, or lambdas, are composed or linked together to perform a sequential computation. Each lambda in the chain takes the output of the previous lambda as its input, passing it along to the next. This allows for the creation of complex operations from simple, modular, and often inline functions.

The core idea is to avoid naming intermediate functions when their sole purpose is to be used in a sequence. Instead of defining separate named functions, a programmer can define a lambda directly where it's needed and pass its result to the next lambda. This can lead to more concise code, especially when dealing with data transformations. For example, in a language that supports it, one might see a structure like `(lambda1 (lambda2 (lambda3 input)))` or a more idiomatic sequential application where the output of one function becomes the input of the next.

While the term "lambda chain" might not be a formal language construct in all functional languages, it effectively describes the programmatic pattern. It's closely related to concepts like function composition and the pipeline operator found in some languages, which explicitly aim to facilitate this style of sequential data processing using anonymous functions. The emphasis is on readability and expressiveness, allowing developers to think about operations as a flow of data through a series of transformations.
