just VS moize

You can roll your own or use a utility library. A simple zero-dependency library would be something like just-group-by [1]. Although I now prefer remeda [2] as it seems to have the best typescript support, especially the strict variants such as `grouBy.strict`.

Tree-shaking doesn't help much when the tree-shaken implementation is so bloated.

Here's the one you referenced, lodash.chunk: https://unpkg.com/lodash.chunk – 140 lines after removing comments and whitespace.

That's pretty small compared to a lot of the lodash utilities. Try spot-checking a few on unpkg.

I prefer angus's `just` utilities: https://github.com/angus-c/just

I absolutely love this. When I need some Lodash alternative I'll usually reference angus-c/just but I am definitely bookmarking this for next time.

The just set of utility functions are really nice to use. https://github.com/angus-c/just

Just doesn't have everything but it's pretty good

One of my favourite "libraries" are the "just" packages, where each part of the library is it's own simple package with zero dependencies (https://github.com/angus-c/just) so you essentially just npm install the specific thing you want - which is generally a single function.

If the code should, as you say, be 5 lines, why take on a dependency at all? By doing so, you end up with a catch-all solution that does almost nothing other than JSON.stringify your args, which is extremely poorly optimized to handle many situations, e.g. one of your args is a primitive and the other is a large config object.

I recently did some testing on the most popular memoization libraries and found moize to be the most fully-featured, actively maintained, and performant.
