[Solved] What does this mean in Javascript: a = a | b [duplicate]

Question

You are doing bitwise-or operation and asigning the result to a.

Example:

if a=5 and b=4 then corresponding bits of their binary representation is operated by an or-operation.

    a=101
    b=100

    a=a|b=101|101=101=5;
