We should look at how existing utility libraries handle this behavior and base any proposals on that IMHO. Underscore and Lo-Dash have [`_.first`](http://lodash.com/docs#first) and [`_.last`](http://lodash.com/docs#last), which both take an optional `callback` parameter, in which case all the first/last `n` elements for which `callback` returns a truthy value are returned. This seems like a sensible thing to add to the proposal. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
