bookChallenge: Discovering Featured Products

Task

  1. The original array is given as products, containing objects representing products with properties name, price, and featured.
  2. Use the find() method to discover the first product in the array with the featured property set to true.
  3. If a featured product is found, log its name and price; otherwise, log a message indicating that no featured product was found.

const products = [ { name: "Laptop", price: 1200, featured: false }, { name: "Headphones", price: 150, featured: true }, { name: "Smartphone", price: 800, featured: false }, { name: "Camera", price: 1000, featured: true }, ]; const featuredProduct = ___.___((product) => ___ === true); if (featuredProduct) { console.log( `Featured product: ${___}, Price: $${featuredProduct.___}` ); } else { console.log(___); }

Expected output:

  1. Use the find() method on the products array and provide a callback function that checks if the featured property of the product object is true.
  2. If a featured product is found, log its name and price; otherwise, log a message indicating that no featured product was found.
