>- complex or clever code; e.g. when I use shift for division by 2, that tends to confuse some coders, or regular expressions in javascript (for some reason JS devs seem scared by regexp) I've found I've never had to use a Regex in Javascript yet. Also I don't think anyone enjoys reading Regex. Writing it is a lot easier. :) Reading `/2` or ` * 2` is more intuitive than `<< 1` or `>>> 1`. Although I learned a new code obfuscation technique! ;) [0] Testing 2^39 and bit shifting is negligibly faster. At lower values (2^4) it is equivalent. For any multiplication/division by a higher power of 2 (2^2, 2^3, 2^4) they become equivalent in speed. 549755813888 * 2 x 1,526,678,336 ops/sec ±0.67% (97 runs sampled) 549755813888 << 1 x 1,562,645,566 ops/sec ±0.26% (99 runs sampled) 549755813888 * 16 x 1,552,125,291 ops/sec ±0.33% (100 runs sampled) 549755813888 << 4 x 1,530,867,164 ops/sec ±0.35% (98 runs sampled) This seems like a case of "being too clever" by trying to optimize something that the compiler can optimize itself.
