Category theory(範疇論)之什麼是Functor, Applicative, Monad, Semigroup, Monoid?

之前曾經寫過一篇 什麼是Monad? ，裡面提到了對於Monad的解釋，而今天進一步解釋這些在Functional Programming中常見到的詞：Functor, Applicative, Monad, Semigroup, Monoid。 透過放在一起比較，讓我們更清楚這些之間的差別與關係。

##Functor

在提到Functor之前，請先了解一下scala中map的作用，map可以讓你傳入一個function，而透過這個function是可以從F[A]轉換成F[B]，這裡的F不管他(就是代表外面的包裝不會變)，而裡面的A型態轉成B型態。

例如：

devster31

- name: set swap_file variable
  set_fact:
    swap_file: /{{ swap_space }}.swap

- name: check if swap file exists
  stat:
    path: "{{ swap_file }}"
  register: swap_file_check

- name: create swap file

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

dawsbot

'use strict';
export default function transformer(file, api) {
  const j = api.jscodeshift;
  const {expression, statement, statements} = j.template;
  const root = j(file.source);

  return root
    .find(j.Program, {
body: [
j.AssignmentExpression
