Bitwise OR Operator (|) (JavaScript)

JavaScript - Internet Explorer 10

Performs a bitwise OR on two expressions.

Copy 
result = expression1 | expression2
result

Any variable.

expression1

Any expression.

expression2

Any expression.

The | operator looks at the binary representation of the values of two expressions and does a bitwise OR operation on them. The result of this operation behaves as follows:

JavaScript
Copy 
0101   (expression1)
1100   (expression2)
----
1101   (result)

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

Supported in the following document modes: Quirks, Internet Explorer 6 standards, Internet Explorer 7 standards, Internet Explorer 8 standards, Internet Explorer 9 standards, Internet Explorer 10 standards. Also supported in Windows Store apps. See Version Information.
