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.

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.

7 The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the …

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

Bitwise operators are useful when manipulating the bits of a number. Look . Otherwise you should use the logical operators. Also the logical operators are short-circuited. For example, if you have and is , …

Jul 22, 2012 · You can still use the bitwise operators as logical operators, its retained operator precedence is the evidence of that. Read out the history of bitwise operator's past life as logical …

The expression x & y will perform a bitwise operation on each individual bit in x and y. So if x is 1010 in binary and y is 1100 then x & y will evaluate to 1000.
