Propositions as types correspondance (PAT) (or Types as Propositions) is one of the most intriguing discoveries of Computer Science. The…

Some time ago I wrote a series about Algebraic effects. I explained then that you could either explain the topic using Math concepts…

In this post I assume you know React and the Hooks API. I also assume a basic knowledge about render and commit phases in Concurrent mode…

Take a simple FP language without polymorphism, just monomorphic types, functions and products. It’s well known that this language can be…

Some time ago, I wrote a tutorial about parser combinators. The tutorial shows ho we can, with a few primitive parsers (e.g. for text and…

OK, continuing my hack to make my focused lens library definetely typed. So far, I have type definitions for base typeclasses/interfaces…

This is the 4th post documenting my tentative to add typings to my focused lens library. So far, I have type definitions for base…

Last post I wrote about my first tentatives to add typings to my focused lens library. I explained the main issue was the lack of Higher…

This is the 3rd post documenting my tentative to add typings to my focused lens library. So far, I’ve been able to add type definitions for…

I remember my first attempts to learn Optics started long time ago, I stopped on basic things due to the lack of good resources at the time…

This is the final part of a series about Algebraic Effects and Handlers. Part 1 : continuations and control transfer Part 2 : Capturing…

This is the third part of a series about Algebraic Effects and Handlers. Part 1 : continuations and control transfer Part 2 : Capturing…

This is the second part of a series about Algebraic Effects and Handlers. Part 1 : continuations and control transfer Part 2 : Capturing…

This is the first post of a series about Algebraic Effects and Handlers. There are 2 ways to approach this topic: Denotational: explain…

In this tutorial we’re going to build a set of parser combinators. What is a parser combinator? We’ll answer the above question in 2 steps…
