Return value

boolean; true or false

Description

or is a logical operator that takes two boolean operands, true or false. The or expression returns true if either operand evaluates to true. If the first operand (the one on the left of the or operator) evaluates to true then the second operand is not evaluated, because the or expression returns true if any of its operands is true (the expression is "short-circuited"). The or operator does not have any equivalent symbols (|, ||), as in Perl or JavaScript. Table 4-3 shows the different combinations that you can use with or and the resulting expression values.
