Is it possible to call two functions simultaneously in Javascript?

I'm trying to write a code that will involve calling two functions at the same time by clicking on a button. I don't know if it's possible, I've only tried calling one function at a time.

As far as i know, since Javascript is single-threaded you can't call two functions at exact the same time, but you can give the impression to do that in some way... in your example i would use the "addEventListener" to manage multiple events on the same element. button.addEventListener("click" funcOne); button.addEventListener("click" funcTwo); *Let me know if i said something wrong*

I discovered that instead of calling two functions at once, which is not working.... I can nest two functions in one... something like this: function myFuncyion() { drawCanvas(); changeStyle(); } Or using EventListener as Maz suggested.. document.getElementById('button').addEventListener('click', myFunction() { drawCanvas(); changeStyle(); });

@Thanh Le Javascript has Web Worker function allow us to create threads from main window to process data asynchronously. To create worker: var worker1 = new Worker("worker.js"); To post message from main thread: use worker1.postMessage(input.value); The web worker would notify main thread using worker1.onmessage event. worker.js receives main thread message using window.onmessage event. And use postMessage function to trigger the worker onmessage event.

@Aina To create asynchronous threads from window, you can consider using Web Worker, more information refer to https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers
