JavaScript object value returns undefined

Question

I assigned a number (audio duration) to a property of an object.

data[i]["audio-duration"] = data[i].audio.duration;

When I console log that object, the audio-duration property shows correctly like:

audio: audio
audio-connection: "2D2NLN7KpO"
audio-duration: 121.99425
audio-name: "Rain Pure"
audio-note: ""
audio-path: "rain.mp3"

But whenever I try to get the audio-duration property like this:

let timelineData = data;
console.log(timelineData[i]["audio-duration"]);

It always returns undefined .

Can anyone help me with this?

Answer 1

The property to use is audioelement.duration and not audioelement.ausio.duration to get audio duration.
