Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !
myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))
| // Let's make it possible to create pure functions even when we're | |
| // dealing with impure operations that would have side effects! | |
| // First we'll need a "Type" that can contain a (sometimes impure) function | |
| function IO(fn) { | |
| if (!(this instanceof IO)) {//make it simpler for end users to create a type without "new" | |
| return new IO(fn); | |
| } | |
| this.runIO = fn;//IO now provides an extra control layer that allows the composition of unexecuted effects |

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of
There's a lot of type terminology and jargon going around when discussing types in Elm. This glossary attempts to list some of the most common type terms along with synonyms, terms from other language communities, examples, and links to more detailed articles on each topic.
A series of exercises to get a feel for how generic types and type variables work in Elm.
For each of these, you are given some code that is not compiling. Your task is to get it
compiling. You can change the body of the function but not the signature. No cheating
with Debug.todo or infinite recursions either 😉
