What does the '|' operator do in javascript?

Question

2 | 3 //Output is 3
7 | 9 //Output is 15

I tried 2 | 3 in the console and I got an output of 3. When I did 7 | 9, the output is 15. How does it work?

It is the OR operator used for Bitwise Operations.

Example :

5 | 1

It will be the same as 0101 | 0001

Result: 0101 = 5
