Miami Tennis Open Seat Selection and Ticketing System Code Analysis

Initial Data and User Input Configuration - The application begins by defining a data set of available seats for the event. The variable availableSeats is an array containing the following strings: "Court1A", "Court1C", "Court1E", "Court2B", "Court2C", "Court2D", "Court3A", "Court3B", "Court4A", "Court4D", and "Court5E". - The program utilizes a prompt function to greet the user with the message: "Welcome to the Miami Tennis Open! Would you like a randomly assigned seat or would you like to choose one? (random/pick)". The result of this prompt is stored in a variable named option. # The setSeat Function Structure - The core logic is encapsulated within a function named setSeat, which accepts two parameters: selectionKind and seatList. - Upon invocation, the function initializes three local variables: 1. endSeat: A string initialized as an empty string "", intended to store the final seat selection. 2. price: A numerical value initialized to $50$. 3. taxRate: A numerical value set to $0.05$ (representing a $5\%$ tax). # Manual Seat Selection Logic - If the selectionKind argument is equal to "pick", the function enters a manual selection routine. - A boolean variable choosing is set to true to control a while loop. - Inside the while (choosing == true) loop: 1. The user is prompted with the message: "Which seat do you want? Available: " concatenated with the seatList. 2. A for...of loop iterates through each element in the seatList. 3. If the user's input (customerSeat) matches an element in the list, endSeat is assigned the value of customerSeat and choosing is set to false to break the loop. 4. If the loop completes without a match (choosing remains true), the console logs: "That seat is not available, please try again.", and the prompt repeats. # Random Seat Assignment Logic - If the selectionKind argument is equal to "random", the function calculates a seat index automatically. - The index is determined using the formula: $\text{Math.round}(\text{Math.random}() \times (\text{seatList.length} - 1))$. - The variable endSeat is then assigned the value at seatList[randomIndex]. # Upgrade and Discount Processing - After a seat is successfully assigned (meaning endSeat is no longer an empty string), the program proceeds to confirm the seat and offer additional options. - Confirmation: The console logs: "Your seat is: " followed by the endSeat. - Premium Upgrade: 1. The user is prompted: "Would you like to upgrade to a premium box seat for $100? (yes/no)". 2. If the user responds with "yes", the price is updated using the formula $price = price + 100$, and the console logs: "Premium box upgrade confirmed for " + endSeat + ".". 3. Otherwise, the console logs: "Standard seating confirmed for " + endSeat + ".". - Senior Discount: 1. The user is prompted for their age: "How old are you? You may qualify for a special discount!". 2. If the age provided is greater than or equal to $65$, a discount is applied. 3. The logic subtracts from the price: $price = price - 15$. 4. Note: Despite the $15$ deduction in code, the console logs the following message: "Senior discount applied: -$8.50". 5. If the age is under $65$, the console logs: "Sorry, you did not qualify for the senior discount.". # Final Financial Calculations and Output - The function calculates the final costs using the following steps: 1. Tax Amount Calculation: $\text{taxAmount} = price \times taxRate$. 2. Tax Rounding: To ensure two decimal places, the code uses $\text{taxAmount} = \frac{\text{Math.round}(\text{taxAmount} \times 100)}{100}$. 3. Grand Total Calculation: $\text{grandTotal} = price + \text{taxAmount}$. 4. Total Rounding: Similarly, the total is rounded using $\text{grandTotal} = \frac{\text{Math.round}(\text{grandTotal} \times 100)}{100}$. - Final Display: The program outputs three final lines to the console: 1. "Subtotal: $" + price 2. "Tax: $" + taxAmount 3. "Your full total with tax is: $" + grandTotal + ". Have fun! Goodluck with meeting some tennis players!". # Error Handling and Initialization - If the endSeat variable remains empty (indicating the initial selection conditions were not met), the else block executes, logging: "Something went wrong. Please refresh and retry.". - The entire process is triggered by the final line of the script: setSeat(option, availableSeats);, which passes the initial user choice and the array of seats into the function logic.
