Algebraic Effects in JavaScript part 1 - continuations and control transfer

This is the first post of a series about Algebraic Effects and Handlers.

There are 2 ways to approach this topic:

Denotational: explain Algebraic Effects in terms of their meaning in mathematics/Category theory
Operational: explain the mechanic of Algebraic Effects by showing how they operate under a chosen runtime environment

Both approaches are valuables and give different insights on the topic. However, not everyone (including me), has the prerequisites to grasp the concepts of Category theory and Abstract Algebra. On the other hand, the operational approach is accessible to a much wider audience of programmers even if it doesn't provide the full picture.

The originality of these Gists varies drastically. Most are inspired by the work of others, in that case, all merit goes to the original authors. I have linked everything used as reference material on the Gists themselves.

Haskell

In this video we come across about 50 online resources for category theory:

I quickly comment on about 20 major ones. I link to the university sites, arXiv sites or Amazon page - most of the mentioned books are online available.

Here's another category theory list on github

A Taxonomy of Self-Types

Part I: Introduction to Self-Types

Datatypes in the Formality programming language are built out of an unusual structure: the self-type. Roughly speaking, a self-type is a type that can depend or be a proposition on it's own value. For instance, the consider the 2 constructor datatype Bool:

	set mouse=
	set nomodeline
	set tabstop=2 shiftwidth=2 expandtab
	" Show tabs.
	set list listchars=tab:>\
	set linebreak
	set ignorecase wildignorecase
	set undofile
	set splitright

	#
	# ~/.bashrc
	#

	# If not running interactively, don't do anything.
	[[ $- != i ]] && return

	shopt -s histappend
	HISTSIZE=''
	HISTFILESIZE=''

	# - Find phrase and add to a temporary file
	# - Create cards and add it to `Stage 0` deck
