var a1 ="true"; var a2 ="false"; Boolean() function in JavaScript: Boolean function returns the boolean value of variable. It can also be used to find boolean result of a condition, expression etc. Note: A variable or object which has value are treated as true boolean values.

valueOf(boolean arg) returns the value assigned to the Boolean variable. If true value is assigned then true is returned else, false. To assign any value to the property, we are using setProperty() method of System class.

To add boolean type to function return value first, declare the function, then add a : symbol (colon) after the parameters opening and closing brackets () and then type the word boolean to indicate that the function's return value is of boolean type.

It's a boolean result of an evaluation - true or false . If it's true, do something. Using it with return returns that boolean result to the caller.
