Before Go 1.18 there was no type-safe way to share that code, so the ecosystem split into two camps: reflection-based helpers that work with any type but panic at runtime, and hand-written per-type functions that are safe but tedious. Generics changed the calculus in 2022 — and by 2026 the landscape has consolidated around three libraries with very different philosophies: <strong>samber/lo</strong> (21,412 stars, a Lodash-style toolbox built on generics), <strong>go-funk</strong> (the reflection-era veteran, now effectively dormant), and <strong>pie</strong> (a focused, type-safe slice-and-map library). Here is how they compare with live repository data and real code, and which one you should reach for in your next module.</p>
