Bundle Footprint
With its modern implementation, es-toolkit significantly reduces its bundle size, cutting it down by up to 97% compared to other libraries like lodash.
This makes es-toolkit the most efficient in terms of bundle size, with some utility functions being as small as less than 100 bytes.

Bundle Size Test Method
Our bundle size is measured using esbuild 0.23.0, by analyzing the size of code like the following:
tsx
import { chunk } from 'es-toolkit';
// or import { chunk } from 'lodash-es';
console.log(chunk);See our bundle size benchmark code for details.
