Questions about common FP functions

Hi @mobily, the library looks really interesting! I’m quite interested in trying it out for future projects. I just have a couple of questions about certain functions, and I hope this is the right place to ask.

1. How would you do Clojure’s assoc and dissoc with ts-belt? Would it have to be D.merge(m, {k: v}) and D.rejectWithKey(m, (_, key) => key == k)?
2. I noticed that D.xxxWithKey’s signature is (v, k) instead of the usual (or rather what I would expect to be) (k, v). Is that just a matter of personal preference or rather a convention from another library/language that I’m not familiar with?
3. On Remeda, the doc says “Due to the lazy evaluation, it’s also unclear how to use some utility functions within the pipeline.” Does this mean that ts-belt does eager evaluation? So something like, say, pipe(m, D.toPairs, A.take(2)) would iterate through all the key-value pairs first before taking the first two elements?

Also, something like Remeda’s mapping doc would be very helpful to newcomers! I’m happy to chip in if you think it’d be useful.

ad 2. it’s been fixed and published in v3.1.1 🚀

👋 hey again @anthony-khong!

I’m curious to know what you actually do during development!

I did some changes to improve this process, so basically, for development purposes, you can use the following commands:

yarn build dev -n Dict -t set

⬆️ this command will build a single module (in this case Dict) and run set tests

yarn test run -f set -n Dict

⬆️ this command will be useful if you change a single test file (in this case Dict/set.test.ts)
