Why can't JavaScript .play() audio files on iPhone safari?

Question

I\'ve got a JavaScript web app working that plays some audio periodically like this:

var SOUND_SUCCESS = new Audio(\'success.mp3\');
SOUND_SUCCESS.play();

To add to xingliang cai's response, here's a code sample I got to work for me:

const soundEffect = new Audio();

// onClick of first interaction on page before I need the sounds
soundEffect.play();

// later on when you actually want to play a sound at any point without user interaction
soundEffect.src = 'path/to/file.mp3';
soundEffect.play();
