Yes, you are of course correct. What I was doing in the originally cited code was illustrating using how `reduce(..)` by its nature supports the adjacency check, instead of using indexes and manual `i-1` type logic. IOW, I initially wanted to avoid the ugly `i-1`, and I traded that for the unfortunate lack of early exit necessitating the equally ugly `prev === false`. :/ _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
