2015-4-19 · Bitwise operators will certainly be faster but only linearly and not by much. You'll probably save a few milliseconds (unless you're processing HUGE amounts of data in Javascript, which is most likely a bad idea anyway). You should think about profiling other code in your loop to see what's slowing it down the most.
Get PriceThe JavaScript Bitwise Operators perform bit operations. All the decimal values converted into binary values (sequence of bits, i.e., 0100, 1100, 1000, 1001, etc.).
