JavaScript Concurrent Flow-Control Framework Based on Node.js

Because of the asynchronous characteristic of I/O,Node.js is quite suitable for developingserver-side Java Script applications. To implement concurrent asynchronous I/O control,developers haveto write tedious code manually,it becomes a barrier to developers. Based on the concurrent counter,aconcurrent flow- control framework can be constructed. The framework achieved concurrent controlbetween multiple asynchronous I/O in a direct viewing way. Thus,it benefits server- side JavaScript developments and also promotes the efficiency of development.
