How would you call the orderPizzas function to log 'You'll need to order 6 pizzas.' to the console?

To log 'You'll need to order 6 pizzas.' to the console, it's essential first to understand the relationship between the number of pizzas being ordered and the expected output string. The statement suggests that regardless of the actual amount of input, the function should return the phrase that indicates the need for 6 pizzas.

If the internal logic of the orderPizzas function is designed to calculate or process incoming numbers to derive the final output, options that lead to an output demonstrating the need for 6 pizzas would be appropriate.

In this context, calling orderPizzas(18) implies a computation or manipulation inside the function that results in the realization that 6 pizzas are needed. The choice to call with 18 might indicate that the function is designed to take a certain parameter and return the necessary quantity based on preset calculations or conditions coded within the function.

Thus, calling orderPizzas(18) effectively logs the appropriate message since it correlates with the function's intention to output a statement regarding pizza quantities needed, despite differences in how the input could yield that output. The focus then is on understanding the logic that connects the function parameter to the desired console output.
