Not for the Data use-cases. Strings are used for binary data, which is tying our hands in supporting UTF-16 properly. Separate issue but we should not complicate String further IMHO. > But I also regret String not being and Array. I agree with Maciej that having mutating methods be no-ops or throwers strongly suggests we not mix Array and String directly. Being able to apply non-mutating Array methods to string (primitive, even) arguments is ok. Splitting a string into an Array and mutating, then joining -- very ok. But I don't see why you want String to *be* (is-a) an Array. > Others must have too, because at one point I'm sure there was a > proposal to make [] on string mean charAt? David Flanagan beat me to it: in ES5 and most browsers. /beReceived on Friday, 6 November 2009 18:48:32 UTC
