Sort by field

We've got an array of objects to sort:

let users = [
  { name: "John", age: 20, surname: "Johnson" },
  { name: "Pete", age: 18, surname: "Peterson" },
  { name: "Ann", age: 19, surname: "Hathaway" }
];

The usual way to do that would be:

// by name (Ann, John, Pete)
users.sort((a, b) => a.name > b.name ? 1 : -1);

// by age (Pete, Ann, John)
users.sort((a, b) => a.age > b.age ? 1 : -1);

Can we make it even less verbose, like this?

users.sort(byField('name'));
users.sort(byField('age'));

So, instead of writing a function, just put byField(fieldName).

Write the function byField that can be used for that.
