This article focuses on "what are the bitwise operators of JavaScript". Friends who are interested may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what the bitwise operators of JavaScript are.

JavaScript is described by bitwise operator name & bitwise and if both bits are 1, each bit is set to 1 | Bitwise or if one of the two bits is 1, each bit is set to 1 ^ different by bit or if only one of the two bits is 1, each bit is set to 1 ~ does not reverse all bits arithmetic right to move to the right by pushing a copy of the leftmost bit from the left And make the rightmost bit fall off > zero fill move right by pushing zero from the left to the right, and let the rightmost bit fall off.

Example:

Operation result equivalent result 5 & 110101 & 000100015 | 150101 | 00010101 ~ 510010110105 120101 > > 100105 > > 120101 > > 10010 bitwise and

When performing bitwise and operations on a pair of bits, 1 is returned if both bits are 1.

An example of operation:

The result of the operation is 000.It returns 00001.It returns 01000.It returns 01001.It returns 1 bit or 1.

When performing a bitwise or operation on a pair of bits, 1 is returned if at least one of the bits is 1, otherwise 0 is returned:

An example of operation:

Operation result 0 | 0 returns 00 | 1 returns 11 | 0 returns 11 | 1 returns 1

You can try it online.

Bitwise XOR

When performing a bitwise XOR operation on a pair of bits, if the bits are different (or), 1 is returned:

An example of operation:

Operation result 0 ^ 0 returns 00 ^ 1 returns 11 ^ 0 returns 11 ^ 1 returns 1
