[Solved] Change array of objects with array inside, to one object [closed]

by


Use reduce for object creation

reduce takes a function as an argument and this function can take several arguments (at least 2), first is called an accumulator, it contains all sum of all previous calls of this function and the second argument is current, it contains a current value, in this case current object which we want to transform. As you can see, there is a {} in the end of reduce and this is initialValue which means that at first run of that function which is inside reduce, accumulator will be this value, so {} (empty object)

var arr = [
  {
    name: "test",
    options: [
      {id: "1", value: ""},
      {id: "2", value: ""},
      {id: "3", value: ""},
      {id: "4", value: ""}
    ]
  },
  {
    name: "test2",
    options: [
      {id: "12", value: ""},
      {id: "23", value: ""},
      {id: "34", value: ""},
      {id: "45", value: ""}
    ]
  }
]

var obj = arr.reduce((obj1, { name, options }) => ({...obj1, [name]: options}), {})

console.log(obj)
