  },
  
  {
    category: "Mobile",
    products: ["Samsung Galaxy S23", "Apple iPhone 15"]
  }
]

// looping through all array elements in reverse
for (let a = categories.length - 1; a >= 0; a--) {
  // condition criteria
  if (categories[a].products.length > 3) {
    // remove array element
    categories.splice(a, 1)
  }
}
