The definitive algorithm is here: http://people.mozilla.org/~jorendorff/es6-draft.html#sec-object.prototype.tostring For pre-ES6 builtin constructors and prototypes, there is no pre-installed @@toStringTag property, but there are checks for internal structure determining a legacy builtin tag. For example, since `RegExp.prototype` is a plain vanilla object, its builtin tag is "Object". —Claude _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
