As I was Googling, I came by this snippet . var calls = []; function executeNext(next) { if(calls.length == 0) return; var fnc = calls.pop(); fnc(); if(next) { executeNext(true); } } /*To call method chain synchronously*/ calls.push(callMe3); calls.push(callMe2); calls.push(callMe1); executeNext(true); /*To call method chain asynchronously*/ calls.push(callMe3); calls.push(function(){ callMe2(); executeNext(false); }); calls.push(function(){ callMe1(); executeNext(false); }); An array was a perfect fit with the built in push() and pop() function. I also needed something that would work the pop() till the array was empty. As Douglas Crockford says in his wonderful book ' JavaScript: the good parts ', arrays are actually (slightly disguised) objects. So one can simple add to the native methods that the array var...
