I know what most of those words mean, but I have no idea what they mean in that order. This feels symptomatic of the general state of Javascript, where I've not written any for a year or so and am now wildly out of date.

People often complain about how complex it is, but it’s really just a matter of passing endofunctions through transplainer pipelines so that you can asynchronously hydrate the islands.

  Seriously, once you understand the ui as a superposition of entangled complex-valued eigenstates that only collapse into place once an observer visits your page, frontend development becomes so much easier.

  Why would you ever even need to pass an endofunction through a transplainer pipeline? There are far more efficient ways to do async island hydration in Elm.

The thing is — I'm actually quite stupid. I don't even understand what a monad is. I just FP because it's a good tool. So, here's an example. I'm building an automatic storyteller on top of GPT-4 — it's a toy project to build the LLM-based functional library. Here's how the code looks, with comments: https://gist.github.com/golergka/3fdc6b9cf9717bd1c0b315925a85e328 https://gist.github.com/golergka/3fdc6b9cf9717bd1c0b315925a8... This is literally 20 lines of code, and it doesn't take that much to learn to read it easily. When I originally implemented LLM-based applications in Python, it would make about 10 times more, and all the components wouldn't be as modular. I can change the functionality of this code in a very drastic way with minimal code changes and with safety of completely statically type checked code.

  Thing is: you don't read it easily. It's basically a custom DSL bolted on top of Javascript that hides actual functionality beneath an Everest of abstractions. That is, it's a yet another library trying to force Haskell/Haskellisms into Javascript and claiming with no proof other than emotions that it's so much better and more readable than something. Here's an actual readable version of that: try{ return getTurnPromptMessages(state, action) .map(mkCCRequestFromMessages) .map(addSchemaToRequest) .map(handleChatCompletion) .map(extractFirstCompletionChoice) .map(extractChatCompletionMessage) .map(decodeSchema) .map(detectLocation); } catch (e) { mkMessageError(e); } It can be further simplified. For example, you don't need two separate functions to extract the first chat completion message etc. This version: - uses existing language constructs - can be immediately understood even by the most junior devs - is likely to be 1000 times faster - does not rely on an external dependency that currently has 143 issues and every two weeks releases a new version adding dozens of new methods to things Note: one thing I do wish Javascript adopted is pipes: https://github.com/tc39/proposal-pipeline-operator https://github.com/tc39/proposal-pipeline-operator

    Your version doesn't work. * all but the first results are not arrays, so the `.map` function doesn't apply * doesn't handle async operations * catches ALL exceptions here, whereas my code only handles statically typed and well-defined errors * doesn't include the GPT-generated message and messages from the first steps in the error * doesn't include retry functionality I appreciate this argument and time you've taken to read my code and write this counter-argument. Please don't mistake my direct code for animosity, I clearly see that you're a smart person even though I think you're wrong about this. Also, the fp-ts doesn't add any runtime performance overhead here. It's a couple of extra function calls for a call that has an async operation that likely takes 30 seconds (GPT-4 is slow). Obviously, if I was writing code that runs thousands of times per second, I would not use FP.

Really? I feel like Javascript has been more or less the same since we got `class` keyword. People have been using “FP” words like monad or Either in Javascript for more than 10 years. They weren’t mainstream then and they aren’t mainstream now even if you see them written in an HN thread.
