JavaScript Bitwise AND

When a bitwise AND operation is performed on a pair of bits, it returns 1 only if both bits are 1.

Here’s a one-bit example:                                                                                                  

 Here’s a 4-bit example:

JavaScript Bitwise OR

When a bitwise OR operation is applied to a pair of bits, it returns 1 if at least one of the bits is 1.

Here’s a one-bit example:

4 bits example:

JavaScript Bitwise XOR

When a bitwise XOR operation is applied to a pair of bits, it returns 1 if the bits are different.

Here’s a one-bit example:

4 bits example:

JavaScript Bitwise AND (&)

Bitwise AND returns 1 only when both bits are 1.

Example

JavaScript Bitwise OR (|)

Bitwise OR returns 1 if at least one of the bits is 1.

Example

JavaScript Bitwise XOR (^)

Bitwise XOR returns 1 when the bits are different.

Example

JavaScript Bitwise NOT (~)

Example

JavaScript (Zero Fill) Bitwise Left Shift (<<)

This is a zero-fill left shift, where one or more zero bits are added from the right, causing the leftmost bits to drop off.

Example

JavaScript (Sign Preserving) Bitwise Right Shift (>>)

This is a sign-preserving right shift, where copies of the leftmost bit are added from the left, causing the rightmost bits to drop off.
