Testing models is straightforward. Especially because MST provides powerful tools to track exactly how your state changes over time. Track snapshots, action invocations or even patches to verify the correctness of your actions! In this lesson you wil…

It is time to add new entries to the wishlist. We will achieve this by reusing forms and models we've built so far. In this lesson you will learn: MST is not limited to a single state tree. Every model can form a tree on its own Appending model insta…

MST has a pretty unique feature: It allows you to capture private state on models, and manage this state by using lifecycle hooks. For example by setting up a WebSocket connection and disposing of the connection automatically as soon as the instance…

n this lesson, we will set up Hot Module Reloading(HMR), making it possible to load new definitions for React components and MST models and apply them to a running application. In this lesson you will learn: How HMR roughly works How to accept change…

Models are not just a nifty feature for type checking. They enable you to attach behavior to your actions in a straightforward and highly discoverable way In this lesson, you will learn: How to define actions on models How to avoid this issues by usi…

生成树:由图生成的树,由图转化为树,进一步可用对树的相关操作来对图进行操作.最小指的是权值最小: 生成树是边的集合,如下图所示的最小生成树:MST={{a,b},{a,f},{f,c}} 本文主要探讨带权无向连通图(网络)上的最小生成树问题,以及求最小生成树的两个算法. 0. 生成数 n 个顶点的图,有 n−1 棵生成树: 1. 最小生成树 最小生成树有很多实际应用.例如,将网络顶点看做城市,边看做连接城市的通信网,边的权看做连接城市的通信线路的成本,根据最小生成树建立的通信网就是这些城市之间成…

早期的前端是由后端开发的,最开始的时候仅仅做展示,点一下链接跳转到另外一个页面去,渲染表单,再用Ajax的方式请求网络和后端交互,数据返回来还需要把数据渲染到DOM上.写这样的代码的确是很简单.在Web交互开始变得复杂时,一个页面往往有非常多的元素构成,像社交网络的Feed需要经常刷新,展示内容也五花八门,为了追求用户体验需要做很多的优化. 当时说到架构时,可能会想前端需要架构吗,如果需要,应该使用什么架构呢?也有可能一下就想起了MVC/MVP/MVVM架构.在无架构的状态下,我们可以写一个HT…

Redundant data or caching data is a constant source of bugs. MST adheres to the philosophy that no data that can be derived should ever get stored. In this lesson, you will learn how to introduce views that declaratively derive data and which cache d…

给定一个无向图,如果他的某个子图中,任意两个顶点都能互相连通并且是一棵树,那么这棵树就叫做生成树(spanning tree). 如果边上有权值,那么使得边权和最小的生成树叫做最小生成树(MST,Minimum Spanning Tree).       1.prim版本的算法   .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", co…
