# Bitwise AND assignment (&=)

The bitwise AND assignment operator (`&=`) uses the binary representation of both operands, does a bitwise AND operation on them and assigns the result to the variable.

## Syntax

``````x &= y // x = x & y
``````

## Examples

### Using bitwise AND assignment

``````let a = 5;
// 5:     00000000000000000000000000000101
// 2:     00000000000000000000000000000010
a &= 2; // 0
