go-functional
A Go library providing functional-style iterators and consumers to augment the standard library's iter.Seq.
What is go-functional?
go-functional is a Go library that provides a comprehensive set of functional-style iterator utilities to augment the standard library's iter.Seq type. It solves the problem of verbose and imperative data processing by offering chainable and standalone operations like filtering, mapping, folding, and collecting, enabling more declarative and expressive code when working with sequences of data.
Go developers (1.23+) who work with iterators (iter.Seq) and want to write more functional, declarative, and concise data processing pipelines, especially those dealing with slices, maps, channels, or streams.
Developers choose go-functional because it provides a rich, idiomatic, and type-safe functional programming layer on top of Go's native iterators, with both a convenient chainable API (itx) and standard library-compatible functions (it), all without requiring external dependencies.
