samber/lo is a Lodash-style utility library for Go 1.18+ built on generics, providing 300+ type-safe helpers for slices, maps, strings, channels, and functions. It includes subpackages for lazy iteration (Go 1.23+ sequences), in-place mutable operations, and parallel processing with worker pools.

Use cases

• map filter and reduce slices in go without boilerplate
• deduplicate a slice in go
• find contains and group items in a go slice
• parallelize processing of a collection in go
• lazy iterate over sequences in go 1.23
• replace lodash-style helpers in a go project
• in-place slice filtering for performance-critical go code

When to choose

• you want hundreds of type-safe collection helpers beyond Go's stdlib slices/maps packages
• you're coming from JavaScript/Python and miss Lodash-style utilities
• you need concurrent or lazy iteration helpers with zero external dependencies

When to avoid

• you prefer minimal dependencies and only need the few helpers in the standard library
• your team style guide discourages functional-style Go code
• you need reactive processing of infinite event streams (use samber/ro instead)
