I don’t think that anything involving an object that has a [[StringData]] internal slot but has `Number.prototype` in its prototype chain could have an ”intuitive” behaviour... > > > I think this is related to `Array.isArray`.

Try `Number.prototype.valueOf.call(obj)`: it will throw a TypeError if and only if `obj` has no [[NumberData]] internal slot. Ditto for String, Boolean and Symbol. —Claude _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
