Using Reduce To Create Object

reduce.js

Add refs to each element in list using reduce, by creating obj.

list = [
  {
    id: "a",
    firstname: "Robin",
    lastname: "Wieruch",
    year: 1988
  },
  {
    id: "b",
    firstname: "Dave",
    lastname: "Davidds",
    year: 1990
  }
];

const refs = list.reduce((acc, value) => {
    acc[value.id] = createRef();
    return acc;
  }, {});
