SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go developers often write boilerplate loops for Map/Filter/Reduce; samber/lo provides declarative, type-safe transformations that return new collections without mutating inputs.

Core Features & Use Cases

Map, Filter, Reduce, GroupBy, Chunk, Flatten, Uniq, and more for slices and maps
Immutable by default and composable, enabling clear data pipelines
Examples: transforming a list of users into a shortened view or grouping tasks by status

Quick Start

Install lo in your Go module and start chaining Map, Filter, and Reduce to process data.

How do I write declarative Map and Filter functions in Go without boilerplate loops?▼

Yes, samber/lo provides error variants like MapErr, FilterErr, and ReduceErr to handle errors safely during data transformation pipelines without crashing your application.

Does Go support type-safe generic data pipelines for slices and maps?▼

samber/lo transformations are immutable by default, meaning operations like Map and Filter return new collections without mutating the original input slices or maps.
