Object.prototype.__count__

Obsolete since Gecko 2 (Firefox 4 / Thunderbird 3.3 / SeaMonkey 2.1)
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

La propietat __count__ s'utilitzava per emmagatzemar el recompte de les propietats enumerables d'un objecte, però s'ha eliminat.

Sintaxi
