The maximal salary

importance: 5

There is a salaries object:

let salaries = {
  "John": 100,
  "Pete": 300,
  "Mary": 250

Create the function topSalary(salaries) that returns the name of the top-paid person.

  • If salaries is empty, it should return null.
  • If there are multiple top-paid persons, return any of them.

P.S. Use Object.entries and destructuring to iterate over key/value pairs.
