Add property to each object in array.js

// Write a function that takes an array of objects and a string as arguments
// Add a property with key 'continent' and value equal to the string to each of the objects
// Return the new array of objects
// Tipp: try not to mutate the original array

function myFunction(arr, s) {
  return arr.map(obj => ({...obj, continent: s}))
}
