            function validateQubit(qubit) {
                if (typeof qubit !== 'object' || qubit.type !== 'qubit') {
                    throw new Error('Invalid qubit: must be a qubit object');
                }
            }

            try {
                validateQubit(qubit);
            } catch (error) {
                console.error("Validation error:", error.message);
            }
        
        

Developers can also throw custom errors using the "throw" statement, providing descriptive error messages to aid in debugging and troubleshooting. Custom errors allow developers to communicate specific error conditions and guide users towards resolving them effectively.

• Throw Statement: Generate and throw a custom error with a specified error message.

        
            // Example QuantumScript throwing error with specific message
            if (qubit === undefined) {
                throw new Error('Qubit is undefined: cannot perform measurement');
            }
