Comment by Razak Wasiu on "What's the difference between Python's Twisted and Node.js Event Loop?"

I am trying to address this as I understand the concept. So, in case this not what you had in mind, feel free to point out. Firstly, I would shoot straight to the basic difference.

Node.js is an event loop that is set from start to be async. It's written in low level in C/C++ and wrapped around JS companions. Node runs on Chrome V8 engine, which allows it to achieve fast performance and features .

Example:

app.use('/', function( req, res ) {
	doSomething(req,res,next()) ;
	doSomethingAgain(req,res,next()) ;
	doFinale();
});

You need to use callbacks to perform a task once a previous task completes.
Event Loop maintains a list of callbacks that need to be called.
So, you can trigger an async task and forget about it. Node.js will call the specific callback when the task completes.

I would only speculate on the python event loop(twisted style), as I haven't had much exposure to its style, but python is very flexible and allows extensibility. So, if you are starting out, either node or python is fine
