567### Introducing `es-toolkit/compat`
568
569We're introducing `es-toolkit/compat`, a new module designed as a drop-in replacement for lodash. It replicates lodash's API, making it easier to switch between the two libraries.
570
571`es-toolkit/compat` is undergoing rigorous testing using real `lodash` test cases. Initial benchmarks suggest it's typically 5% slower and increases bundle size by 10% compared to the original `es-toolkit`.
572
573This module is intended to facilitate a smooth transition and should be replaced with the original `es-toolkit` for optimal performance once migration is complete.
574
575For more information, see our [compatibility documentation](https://es-toolkit.slash.page/compatibility.html).
