"SnapToLevels"  equivalent in JS API?

In the Silverlight API Map Class , there is a Map.SnapToLevels property which

"Gets or sets whether zooming will snap to scale levels if the map contains cached layers".

I do not see the same property in the JS API,  but I was wondering if someone had found a way to zoom "in between" cached layers in a Tiled Map Service.
