There are a lot of monad tutorials. All of them fail due to the "Monad Curse": when someone understands what it is then this person is not able to explain this concept to others.

This article goes another way: it finds the simple code examples where you already use monads without noticing.

Awesome read!

Have you heard about algebraic effects?

The name might be a bit intimidating but the idea is simple. If you’re familiar with try / catch blocks, you’ll figure out algebraic effects very fast.

Dan Abramov (React / Redux core) shares a nice tutorial about this topic.

​​Daan Leijen - Asynchrony with Algebraic Effects

Daan invented Koka, a strongly typed function-oriented language with (side) effect inference.

This talk will introduce algebraic effect handlers and use their power to write beautiful asynchronous programs, by compiling Koka to #js

This is very controversial and had multiple heated discussions around.

#vue Function API RFC is refactored and renamed to Vue Composition API. There are a lot of changes to the proposed spec. That's what "working with the community feedback" is.

We can now have typed views, forms, models, querysets, and APIs in django and djangorestframework!

Let me introduce django-stubs and djangorestframework-stubs to you.

This article provides a quickstart guide and an example project with everything configured and typed.

Monads should and can be tranformed into different other monads. This article guides you through this process.

- Stricter Generators
- More Accurate Array Spread
- Improved UX Around Promises
- Better Unicode Support for Identifiers
- import.meta Support in SystemJS
- get and set Accessors Are Allowed in Ambient Contexts
- Ambient Classes and Functions Can Merge
- APIs to Support --build and --incremental

​​Nice talk about turning unit tests into property-based tests. That's something every developer should think about: properties of your code, not specific implementation.

#cli

Bloat is an endemic problem in software, but there are a few things that make it a particular challenge for #rust:

Cargo makes it so easy to just reach for a crate.
Generics, particularly monomorphization.
Poor support for dynamic libraries.

standard.js maintainer decided to include ads in the terminal output.

All internet is now going on him. But, his point was missed. He spent more than 3000 unpaid hours to create and maintain popular projects that thousands of people use everyday.

So, maybe that's not so wrong?

Legendary github issue from 2013. When one user suggested that it is better to use Category Theory for bulding #js Promises. His request was declined due to "API simplicity", because monads:

> Totally ignore reality in favor of typed-language fantasy land

We all know that in 2019 Promises in #js are monadic and API was changed. Simple is really hard.
