Re: extension modules
kevin curtis wrote: Python has a concept 'extension modules' where module can be implemented in c/c++. Also the idea of running native code in the browser has been put forward by Google's native client for running x86 in the client. MS - i think - are researching something similar. The idea of running native code securely in the browser is speculative and unproven. Nothing should be standardized in this area unless and until such approaches can be demonstrated to have a reasonable chance of resisting attack. To do so would be to repeat previous mistakes that have led to the insecure web we currently have. c/c++ isn't going anywhere and the relationship between ecmascript and c/c++ is interesting. Are there any proposals for something like 'extension modules' for ES6 or do the variations in the engine implementations preclude such a thing? As far as a foreign function interface for non-web uses of JavaScript is concerned, that is something that might in principle be worth standardizing (probably separately from ES6). However, the internal C/C++ interfaces typically used by current JS implementations are highly error-prone, make too many assumptions about implementation details (particularly memory management), and are not suitable for wider use. -- David-Sarah Hopwood ⚥ http://davidsarah.livejournal.com ___ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
Array#indexOf and Array#lastIndexOf question
I noticed that most Array methods perform [[HasProperty]] checks on the index values. Array#indexOf and Array#lastIndexOf do not. Firefox 3, Safari 4, Chrome 2 all seem to check [[HasProperty]] for Array#indexOf and lastIndexOf. Is this an oversight on the draft or did the browser vendors miss something ? - John-David Dalton ___ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
Could this be removed from Array#concat.
I think that under 15.4.4.4 Array.prototype.concat 5 - b. - iii - 3 - a. Call ToString(n). could be removed as it is performed in c. - John-David Dalton ___ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss

Browser implementations, starting with Firerfox 1.5 / SpiderMonkey (JS1.6), preceded the spec, so the oversight is probably on TC39's part. I don't recall this coming up and a rationale for diverging from the de-facto standard being given. /be ___ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
