These are the bitwise operators, all supported in JavaScript: op1 & op2 -- The AND operator compares two bits and generates a result of 1 if both bits are 1; otherwise, it returns 0.

Bitwise works on the binary level, so 0 on binary would seen as 0000_0000, and (in two's complemented) -1 is 1111_1111, this not 0 flips all the bits to 1s, thus alters 0 into -1.

117 Bitwise operations, including bit shift, are fundamental to low-level hardware or embedded programming. If you read a specification for a device or even some binary file formats, you will see …

Nov 17, 2009 · Bitwise operations in programming languages play a fundamental role when dealing with a lot of applications. Almost all low-level computing must be done using this kind of operations. In all …

What are some real world use cases of the following bitwise operators? AND XOR NOT OR Left/Right shift

Aug 7, 2010 · Related: Bitwise operation and usage for bitwise boolean ops in general, pointing out that they do 32 (or 64 or whatever) separate bitwise boolean operations in parallel.

1 Using bitwise_and, bitwise_or, and bitwise_not you can modify any bit configurations to another bit configurations (i.e. these set of operators are "functionally complete"). However, for operations like …

Mar 25, 2010 · 5 Because ~ is not binary inversion, it’s bitwise inversion. Binary inversion would be ! and can (in Java) only be applied to boolean values.

Aug 24, 2008 · Using bitwise operations for bool helps save unnecessary branch prediction logic by the processor, resulting from a 'cmp' instruction brought in by logical operations.

Jun 21, 2013 · 1 Is there any functional difference between logical and bitwise operators in the following case? Yes, there is (lazy eval as others have pointed out). Any reason to support one or the other? If …
