# es-toolkit
> State-of-the-art JavaScript utility library
es-toolkit is a modern JavaScript utility library that offers a collection of powerful functions for everyday use.
Compared to alternatives like lodash, es-toolkit provides a significantly smaller bundle size (up to 97% less) and 2-3 times faster runtime performance. This is achieved through a modern implementation that leverages the latest JavaScript features.
es-toolkit comes with built-in TypeScript types and has been rigorously tested, ensuring 100% test coverage for maximum reliability.
