Is there a & logical operator in JavaScript?

No, the single & is a bitwise AND operator in JavaScript. The AND gives the result 1 when both inputs are 1 otherwise 0.

Example

var firstValue=5;
var secondValue=4;
var result=firstValue & secondValue;
console.log(result);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo172.js.

Output

This will produce the following output −

PS C:\Users\Amit\javascript-code> node demo172.js
4

The value 5 has the binary 101 and 4 has 100.

 5=          1 0 1
 4=        & 1 0 0
--------------------
             1 0 0             which is again 4.
