Hello, everyone.
The definition of the AnimationPlayer.currentTime attribute reads:
( https://w3c.github.io/web-animations/#dom-animationplayer-currenttime )
currentTime, of type double, nullable
The current time of this player unless this playerhas a pending pause
task, in which case this attribute returns null.
The current time is essentially a time value, which can be resolved or
unresolved. Unresolved time value is by convention equal to null.
There are two parts to the spec: the model and the API. In the model we
talk about unresolved times. In the API, unresolved times are
represented by null values.[1] Since this behavior is specific to the
API, we use null there.
It's a bit confusing but we were asked to split the spec up like this
and I don't know how to make it any more clear.
Best regards,
