How to retrieve value from Js.t object?

[graforlock]

I am using mostjs library and I am new to bucklescript, when a map function returns me

Js.t(< time : int; value : Dom.event >)
in a stamp from

let startLoop = Most.(
  timestamp(start)
  |> map((stamp) => {
    // what to do here?
  })
)

Is there anything I can do to use this object values or convert it? There is absolutely nothing in the docs about this scenario.

If the type is not marked as bs.abstract, then you can retrieve the values by writing stamp##time and / or stamp##value. The docs list it under Object2 nowadays as it’s encouraged to use the abstract way of binding to the object.
