boxlang-functional-programming

What problem does it solve?

Provides a structured approach to using BoxLang's functional programming features such as closures, lambdas, and pipelines to write clean, reusable code.

Core Features & Use Cases

• First-class functions: treat functions as values, pass as arguments, return from functions, and store in variables.
• Closures and Lambdas: closures capture outer scope using => or function keyword; lambdas are deterministic and do not capture outer scope.
• Functional pipelines: map, filter, reduce, flatMap, groupBy, and related array/struct operations; destructuring and spread support.
• Practical usage: compose simple transformations, memoization patterns, and chain operations to build data-processing utilities.

Quick Start

Create a small BoxLang snippet that defines a closure and applies it to map over an array.
