Javascript - how to create an array of objects where the object's keys all have the same value

Question

I created a descending array of integers from the current year to 1930 using moment:

options = Array(moment().year() - 1929).fill().map((_, index) => moment().year() - index)

I'm trying to convert options into an array of objects such that the resulting array is something like this:

[{value: '2018', label: '2018'}, {value: '2017', label: '2017'}, ..., {value: '2', label: '2'}, {value: '1', label: '1'}]

Answer 1

Just .map each item to an object instead of to a single number:

const options = Array(moment().year() - 1929)
  .fill()
  .map((_, index) => {
    const value = moment().year() - index;
    return { value, label: value };
  });
console.log(options);
