Event loop refers to an infinite cycle of actions which is used for processing data based on callbacks and messages.
An event loop watches for I/O and timer state changes. It queues functions while waiting for unavailable resources, then dispatches them when resources are available.
I am hoping someone can help me here.
I have an object that has the ability to have attributes that return coroutine objects. This works beautifully, however I have a situation where I need to get the results of the coroutine object from synchronous…

It is known that node.js internally handles asynchronous calls and the programmer never needs to care about what is going on in the backstage. As far as I know, even if everyone says that node.js is only single thread, internally v8/libuv libraries…
I'm designing event loop for asynchronous socket IO using epoll/devpoll/kqueue/poll/select (including windows-select).
I have two options of performing, IO operation:
Non-blocking mode, poll on EAGAIN
Set socket to non-blocking mode.

Supposed, I have a async function in Node.js, basically something such as:
var addAsync = function (first, second, callback) {
setTimeout(function () {
callback(null, first + second);
}, 1 * 1000);

I discovered by experimenting that creating a timer with a duration of 0 allows me to defer work into the event queue. I really like this feature, because it allows avoiding a lot of nasty reentrancy issues. Is this intentional functionality that…
