Angular 2 add key and value to each array object

Question

I have array of objects :

array = [
  {name: 'name'},
  {name: 'name'},
  {name: 'name'},
  {name: 'name'},
]

I want to add key: '123' to each of them so it would be :

array = [
  {name: 'name', key: '123'},
  {name: 'name', key: '123'},
  {name: 'name', key: '123'},
  {name: 'name', key: '123'},
]

What I've tryed :

checked = false;
     this.editObj.forEach(item => item.push(this.checked))

ERROR : item.push is not a function.

But it isn't working. How to do it in the right way ?

Answer 1

const arr = [
  {name: 'name'},
  {name: 'name'},
  {name: 'name'},
  {name: 'name'},
]

const arr2 = arr.map(x => ({...x , key: '123'}));
