) in Javascript does the same as parseInt?

Using bitwise OR 0 to floor a number
Performs a bitwise OR on two expressions,eg:
console.log(12.22|0) // output --->12
where does the decimal go? it's the same as parseInt function
parseInt(12.22) // output --->12
how does it work?
parseInt is useful in cases where one is parsing strings such as "12px".
For example:
pasrseInt("12px"); // returns 12
However, this doesn't make any sense with bit-wise OR:
"12px" | 0; // returns 0
Performing a bit-wise OR is more like applying Math.floor() to a number -- bitwise operations work on 32-bit integers in Javascript.
