ValueRef()

// First, let's create a simple UDF that returns a value
function getName() {
    return "John Doe";
}
// Create a reference to the getName function using ValueRef()
name = ValueRef(getName);
// Example 1: Basic Usage
writeOutput("Direct function call: " & getName() & "<br>");
writeOutput("Using ValueRef: " & name & "<br>");
// Example 2: Using ValueRef with a more complex UDF
function calculateTotal(price, quantity) {
return price * quantity;
}
// Create a reference with preset values
fixedCalculation = ValueRef(function() {
return calculateTotal(10, 5);
});
writeOutput("Fixed calculation result: " & fixedCalculation & "<br>");
// Example 3: Using ValueRef with a closure
counter = 0;
incrementCounter = ValueRef(function() {
counter++;
return counter;
});
writeOutput("Counter value: " & incrementCounter & "<br>");
writeOutput("Counter value: " & incrementCounter & "<br>");
// Example 4: Using ValueRef in a struct
person = {
firstName: ValueRef(function() {
return "Jane";
}),
lastName: ValueRef(function() {
return "Smith";
}),
fullName: ValueRef(function() {
// Note: This would need to be implemented differently in practice
// as the ValueRef doesn't have access to the other references directly
return "Jane Smith";
})
};
writeOutput("Person's full name: " & person.fullName);
