Logical OR operator.
The || operator performs on the both boolean operands a logical OR operation. The operation results in the value true when one or both of the operands are true. The resulting data type of the operation is always bool. For example:
var bool a = true;
var bool b = false;
var bool c = false;
var bool result = a || b; // result = true
var bool result = b || c; // result = false
