isNull

The isNull function checks if a given value is empty. It takes a single parameter, and evaluates whether it is considered empty. If the value is empty, the function returns true; otherwise, it returns false. This function is useful for validating whether a variable or value holds any data or if it's essentially an empty or null value. It can be employed in conditional statements or validation processes to ensure that a particular variable has meaningful content.
