es-toolkit is a modern, high-performance JavaScript utility library offering everyday functions like debounce, chunk, and pick with built-in TypeScript types. It is designed as a faster, smaller drop-in alternative to lodash, with a full compatibility layer (es-toolkit/compat).
Use cases
- replace lodash with a smaller faster utility library
- debounce and throttle functions in javascript
- manipulate arrays and objects with utility functions
- reduce javascript bundle size from utility imports
- use typed utility functions in a typescript project
- get type guard helpers like isNotNil
When to choose
- you want a lodash replacement with 2-3x better performance and up to 97% smaller bundles
- you need strong TypeScript types and type guards out of the box
- you run modern JavaScript environments (Node.js, Deno, Bun, browsers) and want tree shaking
When to avoid
- you depend on deep lodash-specific edge-case behavior outside the compat layer
- you need utilities beyond the provided array, function, math, object, predicate, promise, and string categories
