In a doubly linked list each node in the list stores the contents of the node and a pointer or reference to the next and the previous nodes in the list. It is one of the simplest way to store a collection of items. In this lesson we cover how to crea…

In a singly linked list each node in the list stores the contents of the node and a reference (or pointer in some languages) to the next node in the list. It is one of the simplest way to store a collection of items. In this lesson we cover how to cr…

Doubly Linked List Your task is to implement a double linked list. Write a program which performs the following operations: insert x: insert an element with key x into the front of the list. delete x: delete the first element which has the key of x f…

[TypeScript] 建置输出单一JavaScript档案(.js)与Declaration档案(.d.ts) 问题情景 开发人员使用Visual Studio来开发TypeScript,可以很方便快速的将项目里的所有TypeScript档案(.ts),一口气全部编译成为JavaScript档案(.js),用以提供html网页使用.但是当软件项目越来越庞大的时候,过多的.js档引用,会增加开发.html档案时的负担;并且每个.js档之间的相依关系,也很容易因为引用顺序的错误,而造成不可预期的…

在 <从 JavaScript 到 TypeScript 系列> 文章我们已经学习了 TypeScript 相关的知识. TypeScript 的核心在于静态类型,我们在编写 TS 的时候会定义很多的类型,但是主流的库都是 JavaScript 编写的,并不支持类型系统.那么如何让这些第三方库也可以进行类型推导呢? 这篇文章我们来讲解 JavaScript 和 TypeScript 的静态类型交叉口 -- 类型定义文件. 这篇文章首发于我的个人博客 <听说>. 前端开发 QQ 群:…
