Challenge: Extract Data with Object Destructuring

Task

Create a script demonstrating object destructuring by extracting properties from the provided movie object and logging them. Specifically, construct a logging message that includes the movie's name, producer, budget, and duration time.


              123456789101112131415
            
const movie = {
  name: "Going in Style",
  producer: "Donald De Line",
  duration: 96,
  budget: "$25 million",
};

// Destructure properties from the `movie` object
const { ___, ___, ___, ___ } = movie;

// Use the extracted properties
console.log(`Name: ${___}`); // Movie name
console.log(`Producer: ${___}`); // Movie producer
console.log(`Duration: ${___} minutes`); // Movie duration time
console.log(`Budget: ${___}`); // Movie budget

Expected output:

Use object destructuring to extract the name, producer, duration, and budget properties from the movie object.
Construct a sentence using the extracted properties to describe the movie.


              123456789101112131415
            
const movie = {
  name: "Going in Style",
  producer: "Donald De Line",
  duration: 96,
  budget: "$25 million",
};

// Destructure properties from the `movie` object
const { name, producer, duration, budget } = movie;

// Use the extracted properties
console.log(`Name: ${name}`);
console.log(`Producer: ${producer}`);
console.log(`Duration: ${duration} minutes`);
console.log(`Budget: ${budget}`);
