facingMode property
The MediaTrackSupportedConstraints dictionary's
facingMode property is a read-only Boolean value which is
present (and set to true) in the object returned by
MediaDevices.getSupportedConstraints if and only if the
supports the facingMode constraint. If the
constraint isn't supported, it's not included in the list, so this value
will never be
false.
You can access the supported constraints dictionary by calling
navigator.mediaDevices.getSupportedConstraints().
