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.
The question is what is actually happening when you trigger 1k-2k outgoing HTTP requests?
I see that it would resolve all the connections easily with 500 connections but moving up towards from there seems to cause problems as the connections are…
I have read a lot of related documents.But I still can't understand how it works.
const fs = require('fs')
const now = Date.now();
setTimeout(() => console.log('timer'), 10);
fs.readFile(__filename, () => console.log('readfile'));

I am building a single player MUD, which is basically a text-based combat game. It is not networked.
I don't understand how to gather user commands and pass them into my event loop asynchronously. The player needs to be able to enter commands at any…
JavaScript's event loop uses a message queue to schedule work, and runs each message to completion before starting the next. As a result, a niche-but-surprisingly-common pattern in JavaScript code is to schedule a function to run after the messages…
So I have just discovered that libuv is a fairly small library as far as C libraries go (compare to FFmpeg). I have spent the past 6 hours reading through the source code to get a feel for the event loop at a deeper level. But still not seeing where…
Currently I'm trying to make it possible to remove work queued through post or dispatch to an io_context. The work is queued by a small amount of queuer groups for which the work shall be removeable all at once:

I'd like to create a library built on top of QTcpServer and QTcpSocket for use in programs that don't have event loops in their main functions (because the Qt event loop is blocking and doesn't provide enough timing resolution for the real-time…
Does anyone know or have good links that explain what iPhone's event loop does under the hood?
We are using a custom event loop in our OpenGL-based iPhone game framework. It calls our game rendering system, calls presentRenderbuffer and pumps events…
I was searching the whole web for an answer but didn't find the solution for my problem. Or maybe I did but because I am a beginner to C++/programming/Qt I didn't understand them.
The closest thing was a question here Using a Qt-based DLL in a…
Let's say I do this:
var timer = setTimeout(function() {
console.log("will this happen?");
}, 5000);
And then after just less than 5 seconds, another callback (from a network event in NodeJS for example) fires and clears…
My Eclipse is used to develop Android Apps. It worked fine until one day, an Unhandled event loop exception is prompt. The log is shown below.
To trigger the error prompt, just unfocus the text editor in eclipse and focus it again, then the prompt…
Let's imagine we have a file containing next JS code:
process.nextTick(()=>{
console.log('nextTick')
})
queueMicrotask(()=>{
console.log('queueMicrotask')
})
console.log('console.log')
and we've set module system to "type": "commonjs" in…
