Copy this into the console of any web page that is interactive and doesn't
do hard reloads. You will hear your DOM changes as different pitches of
audio.

I have found this interesting for debugging, but also fun to hear web pages
render like UIs do in movies.

@R4meau, that's awesome!

Maybe someone makes some chrome extension?

And the bookmarklet version:

javascript:(function(){const%20audioCtx=new(window.AudioContext||window.webkitAudioContext);const%20oscillator=audioCtx.createOscillator();oscillator.connect(audioCtx.destination);oscillator.type="sine";let%20numItems=0;oscillator.frequency.setValueAtTime(1,audioCtx.currentTime);oscillator.start();const%20observer=new%20MutationObserver(function(mutationsList){numItems+=mutationsList.length;oscillator.frequency.setValueAtTime(Math.log(numItems+1)*440,audioCtx.currentTime);setTimeout(()=>{numItems-=mutationsList.length;if(numItems===0){oscillator.frequency.setValueAtTime(1,audioCtx.currentTime)}else{oscillator.frequency.setValueAtTime(Math.log(numItems+1)*440,audioCtx.currentTime)}},100)});observer.observe(document,{attributes:true,childList:true,subtree:true,characterData:true})})();

Maybe someone makes some chrome extension?

Yeah, let's do it... (adding to backlog) 😅

@aibolik Already in the making: https://github.com/r4meau/plink-plonk

Feel free to fork and contribute... or start your own. 😄

I'm gonna go slow on it for now (Sunday only), but I'll accept useful PRs at anytime.

Could anyone add reload support? This is so wonderful 🥰 Maybe via localStorage? Or as Firefox Extension?

Its so helpful to find out the DOM manipulations happening behind the eyes!!. Good job @R4meau
