lodash/fp is an optional distribution of lodash that did what the core library did, but did so in a more flexible, powerful, composeable way that makes it easier to construct powerful functions. it was separate from the core, but based heavily on it. https://github.com/lodash/lodash/wiki/FP-Guide
at the time, nothing was settled. we were in a pioneering mode of building; we didn't know what people would find useful or what the future would hold. there were a lot of different ideas floating around, and lodash was trying to stay the same while also offer a port to this barely-subtly-different paradigm, to see what value might be found there. saying that "introduced" it feels like a crude reduction to me; he allowed people the option they asked for.
i personally think fp - in particular - "pointsfree" fp - has huge down sides to being understandable. but it also is a much more succinct and capable way of expressing things, and multiple times a week i run into situations where auto-currying or reverse args would make the code i write much cleaner & not damage code comprehension.
rather than call fp a fad, & insult the author for ever letting it in, i think there's room to say that it's sad that js had to stay on the lowest common denominator. the future was unable to be changed, the old ways stuck. we lost some really good opportunity & capabilities. that said, i still think the pointsfree style is hugely damaging & responsible for greatly reducing the chances we had to improve. instead, we're not "moving on", we're going back to square 1, to the only thing we've ever known or done. that makes me a little sad, to have the pioneering pack up & move back into the city.
Very much agreed. The amount of mileage we get from using Spread (literally the ...) alone has been amazing. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... Iteration helpers is shipping soon, that'll be a huge help (async iteration helpers will be delayed for a while). https://github.com/tc39/proposal-iterator-helpers .
In the olden days, I feel like the codebases I worked on needed to use .apply() multiple times a week, to figure out some creative way of invoking functions. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... That's all gone now; I'd take even odds that 50% of my team knows .call and .apply.
Chrome 117 is shipping Object.groupBy() and that's gonna be a huge help in eliminating a lot of the last places we end up using lodash. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...
The submitter creating multiple var -> let PRs (one PR per file), was also doing this in other projects, and would've broken some of their users.

And he created multiple PRs there too. And didn't follow their workflow...
