isvalid:- Isvalid is a operator whic returns the true value if a URL has right syntax,and also returns a false if URL has wrong syntax.

in other word we can say that,
The isvalid operator is used to test the validity of a variable or the result type of executing an expression. A boolean value is returned to denote the results of the test. A true is returned if the variable or result type is valid. A false is returned if the variable or result type is invalid.
Do not confuse this operator with the URL.isValid function which is used to validate the syntax of a URL address string.

The classic case of an invalid result type for an expression is dividing by zero. In this example, as expected, the isvalid operator returns a false.
Type of:-The typeof operator is used to determine the type of a given expression. An integer is returned that defines the type.

There are five types recognized by WMLScript:

Type Integer
Integer 0
Floating-point 1
String 2
Boolean 3
Invalid 4
