Show the structure of Bitwise Operations?

JavaScript Bitwise OperationsOperator


Name Description
& AND Sets each bit to 1 if both bits are 1
| OR Sets each bit to 1 if one of two bits is 1
^ XOR Sets each bit to 1 if only one of two bits is 1
~ NOT Inverts all the bits
<< Zero fill left shift Shifts left by pushing zeros in from the right and let the leftmost bits fall off
>> Signed right shift Shifts right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off
>>> Zero fill right shift Shifts right by pushing zeros in from the left, and let the rightmost bits fall off

EXAMPLE:-

Operation


Result Same as Result
5 & 1 1 0101 & 0001  0001
5 | 1 5 0101 | 0001  0101
~ 5 10  ~0101  1010
5 << 1 10 0101 << 1  1010
5 ^ 1 4 0101 ^ 0001  0100
5 >> 1 2 0101 >> 1  0010
5 >>> 1 2 0101 >>> 1  0010
