The OR operation takes two bits and
returns 1 if either of the bits
are 1. Otherwise, it
returns 0.
1 | 1 → 1
1 | 0 → 1
0 | 1 → 1
0 | 0 → 0
Think of it like a bucket with two holes in it. If both
holes are closed, no water comes out. If either hole is
open, or if both are open, water comes out.
When performing OR on two integers, the OR operation is
calculated on each pair of bits (the two bits at the same index in
each number).
5 | 6 // gives 7
// At the bit level:
// 0101 (5)
// | 0110 (6)
// = 0111 (7)
