What does exactly the spec think what an iterable is? As far as I can tell, only `Array.from` and `%TypedArray%.from` test for iterability, and until [bug 2486] is resolved, it is hard for us to guess, because there are really more than one possible answer, e.g.: `Symbol.iterator in obj` and `typeof obj[Symbol.iterator] === "function"`. Section The Iterable Interface [1] define something more restrictive than `typeof obj[Symbol.iterator] === "function"`` and less testable, given the requirements of the returned value of `obj[Symbol.iterator]()`. —Claude [bug 2486] https://bugs.ecmascript.org/show_bug.cgi?id=2486 [1] https://people.mozilla.org/~jorendorff/es6-draft.html#sec-iterable-interface _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
