The most common answer to the 4.4.8 Meal Planner CodeHS is:

function start(){
var vegetarian = "Vegetarian";
var lactose = "lactose intolerant";
var restriction = readLine("Restriction: ");
if(restriction == "vegetarian"){
println("Vegetarian: Veggie burger");
}
if(restriction == "lactose"){
println("Lactose Intolerant: No Cheese");
}
if (restriction == "none"){
println("No restrictions: No alterations");
}
}

** IF THIS DOESNT WORK JUST RELOAD THE PAGE AND TRY AGAIN!!

This “Meal Planner” function is designed to provide meal suggestions based on dietary restrictions. However, there are a couple of improvements that can be made to enhance its functionality and efficiency.

Firstly, the variables vegetarian and lactose are declared but not used in the function. Secondly, the function can be made more efficient by using else if and else statements. This way, once a condition is met, the function won’t needlessly check the remaining conditions. Here’s an updated version of your function:

function start(){
    var restriction = readLine("Restriction: ");
    if(restriction == "vegetarian"){
        println("Vegetarian: Veggie burger");
    } else if(restriction == "lactose"){
        println("Lactose Intolerant: No Cheese");
    } else if (restriction == "none"){
        println("No restrictions: No alterations");
    } else {
        println("Unknown restriction: Consult further");
    }
}

In this revised version:

  • The unused variables vegetarian and lactose are removed for clarity.
  • An else statement is added to handle cases where the input doesn’t match any of the known restrictions.
  • else if is used to make the code more efficient.

This function will now ask the user for their dietary restriction and provide an appropriate response based on their input. If the user’s input doesn’t match any of the predefined restrictions, it will advise further consultation.
