JS is primarily composed of C + + code and JavaScript code, but it uses the Gyp tool (http://code.google.com/p/gyp/) for project management of the source code, which is written in the Python language. On the Windows platform,

Recently saw an article on Javacodegeeks node, Grunt, Bower and yeoman–a modern Web dev ' s Toolkit, this article describes a Web development toolset. It's just that I've been using this toolset to develop Web applications, and I've been trying to write an article summarizing the usage of this development kit, taking this opportunity to take a look at this article and summarize my experience with this tool.In the article, the author uses the angular f

In team development, whether it's the write front (js,css,html) or the back end, we need to solve a problem: how to unify the team code style. This article mainly uses pre-git, eslint, js-beautify implementation code style control.Here are the three tools and how to use them: Pre-gitThis tool can implement the function of Git hook, insert some custom beh

the event mechanism and asynchronous IO model, not JS. But he needs to choose a programming language to implement his idea that the programming language does not have IO capabilities and needs to be able to support the event mechanism well. JS does not have the IO feature, is inherently used to handle DOM events in the browser, and has a large group of programmers, so it becomes a natural choice.As he wish

The framework comes with tools that allow you to seamlessly engage the four technologies of the mean framework, such as MongoDB, Express.js, AngularJS, and node. js, and even other groundbreaking techniques such as bootstrap. It also has a lot of HTML and CSS and other additional JavaScript code to greatly reduce your coding time. However, the fram

When it comes to components, JavaScript does not have this feature. Many functions of Javascript in the past were implemented by different vendors. Components have the following features: . JavaScript does not have a module system. There is no native support for confined scope or dependency management. . JavaScript does not have a standard library. There are no file system APIs in the core library, but these will be available after html5 :). . JavaScript does not have a standard API. . JavaScrip

).Console.log (): Prints characters to the standard output stream and ends with line breaks. If there are multiple parameters, it is output in a format similar to the C-language printf () command. The first argument is a string, and if there are no arguments, only one line break is printed.Console.error (): Same as Console.log () usage, just output to standard error stream.Console.trace (): Outputs the current call stack to the standard error stream.4.2.

Order--The "node. JS self-paced" series of articles will document my learning process for Web development based on node. js.node. JS is a development platform based on the V8 engine that performs JavaScript faster and with good performance, and because it is a language for development in JavaScript, it has a lower lear

website:NPM是随同NodeJS一起安装的包管理工具，能解决NodeJS代码部署上的很多问题，常见的使用场景有以下几种：1. 允许用户从NPM服务器下载别人编写的第三方包到本地使用。2. 允许用户从NPM服务器下载并安装别人编写的命令行程序到本地使用。3. 允许用户将自己编写的包或命令行程序上传到NPM服务器供别人使用。From the point of view of package management, NPM should be a maven similar to Cocoapods,java in iOS. It seems to be a lot better to understand. Detailed usage and principles remain to be delved into.With the development of various web applications, HTML5, small programs, React native a variety of technologies in many areas of wides
