12 };

Explanation:

Step1: Define the getter function

According to the note, the getter function should start with get. So we define get totalRevenue().

get totalRevenue()

Step2: Return the subtraction result

The function needs to return boxOffice - budget. So the complete function is:

get totalRevenue() {
    return this.boxOffice - this.budget;
}

Answer:

// Code will be tested with a different movie
let movie = {
    title: "Pirates of the Caribbean: At World's End",
    director: "Gore Verbinski",
    composer: "Hans Zimmer",
    budget: 300000000,
    boxOffice: 963400000,
    awards: [],
    // Your solution goes here
    get totalRevenue() {
        return this.boxOffice - this.budget;
    }
};
