Answer 1

Working code with ES6:

const input = [
  {
      "selected": true,
      "date": "2021-01-15",
      "selectedColor": "#2ecc71"
  },
  {
      "selected": true,
      "date": "2021-01-16",
      "selectedColor": "#e74c3c"
  },
]

const format = input => {
  const obj = {};
  input.forEach(inp => {
    const { selected, date, selectedColor } = inp;
    obj[date] = { selected, selectedColor };
  });
  return obj;
}

console.log(format(input));
