- Lightdash - A small JavaScript utility library to complement lodash.
- Radash - A drop-in replacement for lodash, also written in ES Modules.
- You might not need lodash - It’s a great website, well crafted, battle tested and with a very skilled and active community contributing. The goal of that project is NOT to provide drop in replacements, but to show how to achieve similar functionalities in plain Javascript, to understand how things work behind the hood.
