again

again
=====

##概况

更加方便灵活地管理一个函数的定时执行和执行次数

##安装

npm install again

##使用
var again = require('again');
var callTimes = 0;
//每执行这个函数都使callTimes 加 1
var addCallTimes = function (callback) {
process.nextTick(function () {
callback(null, callTimes++);
});
}

//每个10ms，执行一遍addCallTimes
var againForever = again(addCallTimes, 10);
againForever(function (err, data) {
console.log(data);
});

//每个10ms，执行一遍addCallTimes,一共执行100词
var againHundredTimes = again(addCallTimes, 10, 100);
againHundredTimes(function (err, data) {
console.log(data);
});
