Proxies are required to update length to be one greater than index (property name-string P such that ToString(ToUint32(P)) == P and ToUint32(P) is not 2^32 - 1) when setting an indexed property. Array's magic [[Put]] is not inherited. /be _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
