  name: 'book',
  colors: 'red, yellow, blue'
  },
  id: 2,
  name: 'book',

  }
 ]

[
  {id: 1,
  name: 'book',
  colors: ['red', 'yellow', 'blue']
  },
  id: 2,
  name: 'book',
  colors: ['red', 'yellow', 'blue']
  }

Answer 1

You can do the following,

 data = [ {'id': 1, 'name': 'book', 'colors': 'red, yellow, blue' }, {'id': 2, 'name': 'book', 'colors': 'red, yellow, blue' } ]; ret = data.map((item) => { return {...item, colors: item.colors.split(',').map(item => item.trim())}; }) console.log(ret);

Answer 2

Strings get into arrays in each object.

 let arr = [ {id: 1, name: 'book', colors: 'red, yellow, blue' }, {id: 2, name: 'book', colors: 'red, yellow, blue' } ] for (let index in arr) { let colorsIntoArr = arr[index].colors.split(','); arr[index].colors = colorsIntoArr; } /* [ { "id": 1, "name": "book", "colors": [ "red", " yellow", " blue" ] }, { "id": 2, "name": "book", "colors": [ "red", " yellow", " blue" ] } ] */ console.log(arr)
