In my proposal it would return the equivalent of `String.fromCharCode('π'[1])`. I think thatβs the most sane behavior in that case. This also mimics the way `String.codePointAt` works in such a case. Hereβs a prollyfill for `String.prototype.at` based on my earlier proposal: https://github.com/mathiasbynens/String.prototype.at Tests: https://github.com/mathiasbynens/String.prototype.at/blob/master/tests/tests.js _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
