Objective: Create a code that can determine whether someone is a student or a guest. And make another code that can determine if you are allowed to ride a roller coaster or not, based from you’re height and from you’re health.

Instructions

1.Open a New Cell set its type to Code

2.Declare a Boolean Variable:

Make a variable named isStudent. Assign it a boolean value of true or false, like this: var isStudent = true;

3.Use an if Statement:

Create a conditional statement to check the value of isStudent.

4.Log a Message if isStudent is true:

Inside the if block, make the message be “Welcome, student!” to the console if isStudent is true.

5.Log a Message if isStudent is false :

Inside the else block, make the message be “Welcome, guest!” to the console if isStudent is false.

6.Run the Code.

    console.log("Welcome, student!");
} else {
    console.log("Welcome, guest!");
}

More instructions:

  1. Open a New Cell set its type to Code

  2. Declare Variables:

Create a variable for Height and set it to a any reasonable number like 5”3. Create a variable for inGoodHealth and set it to a boolean value like this: var inGoodHealth = true;.

  1. Use Boolean Operators:

Create a variable named isEligibleForRidingRollerCoaster and use a combination of boolean operators to evaluate eligibility: Make sure that Height is greater or equal to 5”3 AND if inGoodHealth is true.

  1. Log the Result:

Use an if statement to log a message to show whether the student or guest can ride the roller coaster based on the value of isEligibleForRidingRollerCoaster.

  1. Run the Code.
%%js

⬇︎ Answer key ⬇︎

%%js

const userName = "Mario"; 
let height = 5"3; 
let inGoodHealth = true; 


const isEligibleForRidingRollerCoaster = (height >= 5"3) && inGoodHealth;


if (isEligibleForRidingRollerCoaster) {
    console.log("Congratulations, " + userName + "! You can ride this roller coaster.");
} else {
    console.log("Sorry, " + userName + "you can't ride this roller coaster.");
}
