Check if each item in an array is today's date?

I have an array of objects. Each object has a date property. I am trying to create a function where I append every item to a new array if the item's date is equal to today's date.

Also, I am not sure if the for loop is the most efficient approach for this, this list will never be more than a few hundred items though.

My function:

todayListItems() {
    const todayItems = [];
    const todayDate = moment(new Date()).format('dd-mm-YYYY');
    for (let i = 0; i < myArray.length; i++) {
      const itemDate = moment(myArray[i].date).format('dd-mm-YYYY');
      if (itemDate === todayDate) {
        todayItems.push(myArray[i]);
      }
    }
    console.log(todayItems);
    return todayItems;
  }

This function runs but even if there is an item with today's date nothing will be pushed to the array.

You can use Array.filter() and moment#isSame with the second parameter to limit the granularity to a unit other than milliseconds:

function todayListItems(arr) {
  return arr.filter(obj => moment().isSame(obj.date, 'day'));
}

todayListItems(myArray);

Demo:

function todayListItems(arr) {
  return arr.filter(obj => moment().isSame(obj.date, 'day'));
}

const myArray = [
  { date: '2019-10-14T12:10:00Z'},
  { date: new Date() },
  { date: moment().minutes(120).format('YYYY-MM-DDTHH:mm:ss') },
  { date: new Date('2019-10-23T01:00:00') },
];

console.log(todayListItems(myArray));

You're formatting wrongly. mm is minutes. The formatting should be DD-MM-YYYY, see https://momentjs.com/docs/#/displaying/format/
