# Pend Dead-simple optimistic async helper. ## Usage ```js var Pend = require('pend'); var pend = new Pend(); pend.max = 10; // defaults to Infinity setTimeout(pend.hold(), 1000); // pend.wait will have to wait for this hold to finish pend.go(function(cb) { console.log("this function is immediately executed"); setTimeout(function() { console.log("calling cb 1"); cb(); }, 500); }); pend.go(function(cb) { console.log("this function is also immediately executed"); setTimeout(function() { console.log("calling cb 2"); cb(); }, 1000); }); pend.wait(function(err) { console.log("this is excuted when the first 2 have returned."); console.log("err is a possible error in the standard callback style."); }); ``` Output: ``` this function is immediately executed this function is also immediately executed calling cb 1 calling cb 2 this is excuted when the first 2 have returned. err is a possible error in the standard callback style. ```
