They say that one of the pros of NodeJS is that you use the same language on the back-end and the front-end, so it's easy to share code between them. This sounds great in theory, but in practice the synchronous dependency handling in NodeJS works completely different than any client-side frameworks (which are asynchronous).

Usually that means that you end up copy-pasting your code between your NodeJS sources and your client-side sources, or you use some tool like Browserify, which is brilliant, but they add an extra step in the build process and most likely will conflict with the dependency handling of the framework of your choice (like AnularJS DI). I couldn't look in the mirror if I would call that code sharing.

Fortunately, with a couple of lines of boilerplate code, you can write a module which works in NodeJS and AngularJS as well without any modification.

No globals in the front-end, and dependencies will work. The isNode and isAngular va

近日来自己想基于maven搞一个有多子模块的archetype,就用比较流行的Spring mvc.[archetype] 闲来无事加上Spring security可好? 于是乎加上Spring security之后应用起不来了,日志如下:

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js
