nit: this naming is not super clear, I thought this was splitting by condition like lodash's partition. Maybe we could use something like invertObjectArray or transformObjectsToPropertyArray or pivotObjectArray (like excel pivot) or transposeObjectArray

I initially thought of extractProperties, as in "we are extracting these properties from the array". Wdyt?

Hmm that doesn't feel clear enough still. Maybe extractPropertyArrays? but that also doesn't feel satisfying

I actually think transposeObjectArray is a great name! Will update it.

Here is Claude's argument for transpose 😆 :
Yes, transposeObjectArray is actually a very fitting name! Here's why:
- In mathematics, transposition involves converting rows into columns (or vice versa), which is conceptually similar to what this function does:
// From:
[
{ id: 1, name: 'John' },
{ id: 2, name: 'Jane' }
]
// To:
{
id: [1, 2], // column of ids
name: ['John', 'Jane'], // column of names
rest: [{}, {}] // remaining columns
}
- It's more precise than "partition" because we're not just splitting the data, we're reorganizing it into a different structure

yeah that was my thought process too for that name

nit: maybe this should be an opt-in options prop
