How can I get the nearest date through moment.js?

Question

Dates list:

const datesToBeChecked = [ '2020-07-06', '2020-07-13', '2020-07-20' ]

Date to be checked for

const dateToCheckFor = '2020-07-07';

How can I get the nearest date for the date in the dates array using moment.js?
I want the function to return 2020-07-13 in this case.
I found a couple of answers online but none of them use YYYY-MM-DD format neither moment.js. I want to use moment.js to achieve this, thanks!

You can use the diff method to compare dates.

const datesToBeChecked = ['2020-07-06', '2020-07-13', '2020-07-20']
const dateToCheckFor = '2020-07-07';

let nearestDate;

datesToBeChecked.forEach(date => {
  let diff = moment(date).diff(moment(dateToCheckFor), 'days');
  if (diff > 0) {
    if (nearestDate) {
      if (moment(date).diff(moment(nearestDate), 'days') < 0) {
        nearestDate = date;
      }
    } else {
      nearestDate = date;
    }
  }
});

console.log(nearestDate);
