I only updated remeda, but you can see just updating it makes it narrowly win a few benchmarks.

    ➔ Fastest is remeda

Considering all package versions are from 2021, 3-3.5 years later I think we should be fairer in benchmarking with latest versions.

Hi. I updated all the contender's versions and tested them on my machine(Macbook Pro M2) and these are the results.

    "lodash": "4.17.21",
    "rambda": "9.1.0",
    "ramda": "0.29.1",
    "remeda": "1.47.1"

node version: 20.10

seems that the bold claims that ts-belt said are still valid I guess?

Very very different results than mine also on a Macbook M2 Pro for Remeda, but that may be the nature of benchmarks. Nice job @JUSTIVE

maybe the varied result caused by node version. I'll match to yours and check again.

I re-checked with node 18.19, not much difference from above. Which remeda version are you using? I see some rambda results beat ts-belt, but nothing from remeda. To clarify, I appended the version to each library's name.
