    How Math.random()*6 +1|0 works?

    It looks like
    Math.random()*6 +1|0 works the same as
    Math.floor(Math.random()*6 + 1
    but I do not understand how 1|0 works.

    It is clearer when written
    Code:
    ( Math.random() * 6 + 1 ) | 0 ;
    A bitwise OR operation converts the result to an integer, removing the decimal fraction.
