    Project mention: What is this callback in async.parallel function? | reddit.com/r/learnprogramming | 2022-08-08

    Have you checked out the docs for the async library they are using?

    Project mention: Oven: The Company Behind Bun | news.ycombinator.com | 2022-08-23

    It might, if the code can be optimized. There are all sorts of reasons why it might not. For example, at one point in time, a switch statement with more than 128 cases could not be optimized.

    Project mention: How to make Ajax request through NodeJS to an endpoint | reddit.com/r/codehunter | 2023-01-25

    How can I achieve this in NodeJS. I wonder if Q Library can be utilized in this case

  • co

    Project mention: What's another way to write "for await" that is es6 compatible? | reddit.com/r/learnjavascript | 2022-06-25

    Given that the semantics of async functions are quite similar to generator functions, you can use a library the uses the latter to emulate the former – e.g.: https://github.com/tj/co

  • Javascript State Machine

    A javascript finite state machine library

  • when

    A solid, fast Promises/A+ and when() implementation, plus other async goodies.

  • Fluture

    :butterfly: Fantasy Land compliant (monadic) alternative to Promises

    Project mention: FP for web/mobile apps in 2022? | reddit.com/r/functionalprogramming | 2022-08-02

    I think that it is fine to code perfectly functional apps using TypeScript with React Native and React. You will have a huge community to support you with documentation, libraries, and available labor. Yes, the language has a lot of soundness holes and misses a lot of useful features like pattern matching or type classes but, for me, it is a valid trade-off. There are libraries for better FP programming in TypeScript like fp-ts, io-ts, and fluture.

  • InfluxDB

  • pify

    Promisify a callback-style function

    Project mention: My theory on why so many people are bad at coding. | reddit.com/r/ExperiencedDevs | 2022-08-12

    What's probably got your shorts in a knot is the contents of the node_modules directory. That directory is a cache for mode.js modules so the tutorial can function standalone without having to install anything else. Treat it as you would object code. I pulled a half-dozen of those modules at random and went to their repositories. Every one of them had unit tests: block-stream, graceful-fs, lowercase-keys, minimist, pify and safe-buffer. Nobody sane ships unit tests with their executables.

  • p-map

    Map over promises concurrently

  • zen-observable

    An Implementation of Observables for Javascript

  • contra

    :surfer: Asynchronous flow control with a functional taste to it

  • suspend

    Callback-free control flow for Node using ES6 generators.

  • delay

    Delay a promise a specified amount of time

    Project mention: 11B ethereum hardhat : Create task | dev.to | 2022-07-23

    Manually creating a Promise can look challenging, but you don't have to do that if you stick to async/await and Promise-based APIs. For example, you can use the npm package delay for a promisified version of setTimeout.

  • js-csp
