Why Pithos is Competitive
Modern JavaScript target. Pithos targets ES2020+. No polyfills, no legacy compatibility layers.
Pure functions. Each utility is a standalone function. No classes, no prototypes, no hidden dependencies.
True tree-shaking. Import what you use, ship what you import:
// Only chunk ends up in your bundle
import { chunk } from "pithos/arkhe/array/chunk";
Why Lodash is Larger
Lodash pioneered the JavaScript utility ecosystem and remains widely used. Its larger bundle size comes from a deliberate choice: broad compatibility across environments, including ES5 and older runtimes. Every function carries internal utilities and polyfills to ensure consistent behavior everywhere.
That legacy support has a cost. Lodash is 10-50x larger than Pithos for most utilities. Not because it's poorly written, but because it solves a different problem: universal compatibility vs. modern-first.
es-toolkit
es-toolkit is a modern Lodash replacement with good tree-shaking. Pithos is generally 10-30% smaller on individual functions.
es-toolkit/compat is their Lodash compatibility layer, significantly larger due to legacy API support.
