How to set volume of audio object?

Question

I know that i can create an audio object like this:

var audio = new Audio("test.wav"); 

And i know how i can play the audio:

audio.play(); 

I used the following for loop to output all functions from audio:

var myAudioObject = new Audio();    for (var key in myAudioObject)  {     if (typeof myAudioObject[key] === "function")     {         console.log(key);     }  }

But there is no setting for volume. Is it possible to change the volume in the audio object?

HINT

It was my fault. If i replace function in my for loop with number then i find volume.

var myAudioObject = new Audio();    for (var key in myAudioObject)  {     if (typeof myAudioObject[key] === "number")     {         console.log(key);     }  }

Answer 1

It's not a function, it's a property called volume.

audio.volume = 0.2; 

HTMLMediaElement volume ^MDN

Answer 2

i use:

let music = new audio({     loop: true,     volume: 1,     src: ['/yourSounds/music.mp3'] }) 

it is easer to type
