你可能其實不懂繼承 - 什麼是 Covariance 跟 Contravariance

在近代高等程式語言快（ㄏㄨˋ）速（ㄒ一ㄤ）演（ㄔㄠ）化（ㄒㄧˊ）的狀況下，很多 strong type 的程式語言都開始有了 generic 的設計， 舉例來說：

（這只是大略分類）

• Mobile: Swift, Kotlin
• Frontend: Flowtype, TypeScript
• 後端語言：Python (pyre), Scala, C#, Java （沒錯！現在連 Java 都有）

Here are some of the examples of Reactive Programming libraries I've found in Purescript and what I've thought about them so far:

Purescript Behaviors: https://github.com/paf31/purescript-behaviors

I've never used a library with truly continuous Behaviors, so this was really neat to try out for me. Really nice to use and comes with utilities for working with browser events already, and gives you good Event modules for picking your sampling options as necessary.

I will probably use this library for all of my future uses.

Purescript Signal: https://github.com/bodil/purescript-signal

Settings

1. Create a project in XCode with the default settings
   • iOS > Application > Single View Application
   • Language: Swift
2. Under project General settings, add ReactKit to Linked Framework and Libraries
   • + > Add Other... and choose /path/to/react-native/ReactKit/ReactKit.xcodeproj
3. Now ReactKit would have been imported. Link it by choosing it from the list.
   • + > lib.ReactKit.a
4. Under project Build Settings,
