map() – nocin.eu

Recently I hat to create an array of objects from another array of objects to change some property names and to enrich it with some values. To iterate over the array I used the map() function. But when trying to return the new object using the brackets {}, the map function instead expects me trying to write a function… Therefore you need to wrap the return object in ()

const aPersons = [{
  id: 1,
  name: 'max'
}, {
  id: 2,
  name: 'peter'
}]

const aResult = aPersons.map(person => ({ value: person.id, text: person.name, someboolean: true }))
console.log(aResult)
