While terseness clearly contributes to understandability, regularity and simplicity do too. When these conflict, we should be very careful about sacrificing regularity. Currently is JS, x['foo'] and x.foo are precisely identical in all contexts. This regularity helps understandability. The terseness difference above is not an adequate reason to sacrifice it. > > Kris Kowal > _______________________________________________ > es-discuss mailing list > [email protected] > https://mail.mozilla.org/listinfo/es-discuss > -- Cheers, --MarkM
