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.
