Bubble Sort for Objects in an Array Using JavaScript

Suppose, we have a constructor class that creates Shoe objects like this −

class Shoe {
   constructor(name, price, type) {
      this.name = name;
      this.price = price;
      this.type = type;
   }
};

We are using this class to fill an array with objects like this −

const arr = [
   new Shoe('Nike AirMax 90', '120', 'Casual'),
   new Shoe('Jordan Retro 1', '110', 'Casual'),
   new Shoe('Jadon Doc Martens', '250', 'Seasonal boots'),
   new Shoe('Adidas X Ghosted', '110', 'Athletic'),
   new Shoe('Nike Vapourmax Flyknit', '250', 'Casual'),
   new Shoe('Aldo Loafers', '130', 'Formal'),
   new Shoe('Timberlands', '199', 'Seasonal boots'),
   new Shoe('Converse High Tops', '70', 'Casual'),
   new Shoe('Converse Low Tops', '80', 'Casual'),
   new Shoe('Adidas NMDs', '110', 'Athletic'),
   new Shoe('Heels', '130', 'Formal'),
   new Shoe('Nike AirForce', '150', 'Casual')
];

We are required to write a JavaScript function makes use of precisely the Bubble Sort algorithm to sort this array of objects based on the price property of the objects.

Example

The code for this will be −

class Shoe {
   constructor(name, price, type) {
      this.name = name;
      this.price = price;
      this.type = type;
   }
};
const arr = [
   new Shoe('Nike AirMax 90', '120', 'Casual'),
   new Shoe('Jordan Retro 1', '110', 'Casual'),
   new Shoe('Jadon Doc Martens', '250', 'Seasonal boots'),
   new Shoe('Adidas X Ghosted', '110', 'Athletic'),
   new Shoe('Nike Vapourmax Flyknit', '250', 'Casual'),
   new Shoe('Aldo Loafers', '130', 'Formal'),
   new Shoe('Timberlands', '199', 'Seasonal boots'),
   new Shoe('Converse High Tops', '70', 'Casual'),
   new Shoe('Converse Low Tops', '80', 'Casual'),
   new Shoe('Adidas NMDs', '110', 'Athletic'),
   new Shoe('Heels', '130', 'Formal'),
   new Shoe('Nike AirForce', '150', 'Casual')
];
const bubbleSort = (arr = []) => {
   let swapped;
   do {
      swapped = false;
      for (let i = 0; i < arr.length − 1; i++) {
         if (+arr[i].price > +arr[i + 1].price) {
            let temp = arr[i];
            arr[i] = arr[i + 1];
            arr[i + 1] = temp;
            swapped = true;
         };
      };
   }while (swapped);
}
bubbleSort(arr);
console.log(arr);

Output

And the output in the console will be −

[
   Shoe { name: 'Converse High Tops', price: '70', type: 'Casual' },
   Shoe { name: 'Converse Low Tops', price: '80', type: 'Casual' },
   Shoe { name: 'Jordan Retro 1', price: '110', type: 'Casual' },
   Shoe { name: 'Adidas X Ghosted', price: '110', type: 'Athletic' },
   Shoe { name: 'Adidas NMDs', price: '110', type: 'Athletic' },
   Shoe { name: 'Nike AirMax 90', price: '120', type: 'Casual' },
   Shoe { name: 'Aldo Loafers', price: '130', type: 'Formal' },
   Shoe { name: 'Heels', price: '130', type: 'Formal' },
   Shoe { name: 'Nike AirForce', price: '150', type: 'Casual' },
   Shoe { name: 'Timberlands', price: '199', type: 'Seasonal boots' },
   Shoe { name: 'Jadon Doc Martens', price: '250', type: 'Seasonal boots'},
   Shoe { name: 'Nike Vapourmax Flyknit', price: '250', type: 'Casual' }
]
