Can't find any documentation on "duration" option/function

Is "duration" parameter expressed as? seconds, frames, milliseconds?
When using an array of "to" values, how Tweenjs handle the duration parameter?
Thank you

1. Is "duration" parameter expressed as? seconds, frames, milliseconds?
   The duration parameter in Tween.js is expressed in milliseconds. For example, a duration of 1000 means the animation will take 1 second to complete.

2. When using an array of "to" values, how Tweenjs handle the duration parameter?
   When you provide an array of to values, Tween.js will treat it as a sequence of tweens. Each segment will have its own duration and interpolation will occur sequentially.

   new TWEEN.Tween(object)
     .to({ x: [100, 200, 300] }, 6000) // Total duration is 6000 milliseconds
     .start();

   In this example, the total duration is 6000 milliseconds (6 seconds). Tween.js will divide the total duration by the number of segments (3 in this case), so each segment will have a duration of 2000 milliseconds (2 seconds).
