Find within array of objects the item having maximum value of certain property and return another property of that item

Question

Trying to create a function to return the Name if the price is the highest using javascript. Still learning.

  {
    Name: "Effective Yoga Habits",
    type: "book",
    price: 10.99
  },
  {
    Name: "Yoga kit",
    type: "product",
    price: 199.99
  },
  {
    Name: "Medative surroundings",
    type: "CD",
    price: 6.00
  }
]

If anyone can help I would appreciate it. Thank you in advance

You may use Array.prototype.reduce() to traverse your array and have accumulator to store the record with greatest price value:

const src = [{Name:"Effective Yoga Habits",type:"book",price:10.99},{Name:"Yoga kit",type:"product",price:199.99},{Name:"Medative surroundings",type:"CD",price:6.00}],

    result = src
      .reduce((r, {Name,price}) => 
        price > r.price ? {Name,price} : r)
      .Name
    
console.log(result)
