Bitwise OR Assignment Operator (|=) (JScript 5.6) 

Performs a bitwise OR on the value of a variable and the value of an expression and assigns the result to the variable.

result |= expression

Arguments

• result
  Any variable.

• expression
  Any expression.

Remarks

Using this operator is exactly the same as specifying:

result = result | expression

The |= operator looks at the binary representation of the values of result and expression and does a bitwise OR operation on them. The result of this operation behaves like this:

0101    (result)

1100    (expression)

----

1101    (output)

Any time either of the expressions has a 1 in a digit, the result has a 1 in that digit. Otherwise, the result has a 0 in that digit.
