Asynchronous function can improve the responsiveness and scalability of the application and service. C# 5.0 introduces asynchronous function to greatly simplify the async programming model.

When you build an application with JavaScript, you always want to modularize your code. However, JavaScript language was initially invented for simple form manipulation, with no built-in features like module or namespace. In years, tons of technologies are invented to modularize JavaScript. This article discusses all mainstream terms, patterns, libraries, syntax, and tools for JavaScript modules.

Monad is a powerful structure, with the LINQ support in C# language, monad enables chaining operations to build fluent workflow, which can be pure. With these features, monad can be used to manage I/O

As fore mentioned endofunctor category can be monoidal (the entire category. Actually, an endofunctor In the endofunctor category can be monoidal too. This kind of endofunctor is called monad. Monad i

Given monoidal categories (C, ⊗, IC) and (D, ⊛, ID), a strong lax monoidal functor is a functor F: C → D equipped with:

A functor is the mapping from 1 object to another object, with a “Select” ability to map 1 morphism to another morphism. A [bifunctor](http://en.wikipedia.org/wiki/Functor#Bifunctors_and_multifunctors

If F: C → D and G: C → D are both functors from categories C to category D, the mapping from F to G is called and denoted

In category theory, is a ) from category to category. Giving category C and D, functor F from
