Removing dates that are in the past from an array of objects

Question

Removing dates that are in the past from an array of objects

How can I filter out objects with a date earlier than today's date? For example, if today is: 2022-08-17 and I have { date: "2022-08-15" } in my array of objects.

let todayDate = new Date().toISOString().slice(0, 10);

let arr = [
  { date: "2022-08-15" }, // todayDate is 2022-08-17 so this object should be removed
  { date: "2022-08-31" },
  { date: "2022-10-19" },
  { date: "2022-10-27" },
];

// expected result after filtering

// let arr = [
//   { date: "2022-08-31" },
//   { date: "2022-10-19" },
//   { date: "2022-10-27" },

To find dates greater than the current date, one approach is to use the Date constructor to parse the date and compare it with the current timestamp:

let arr = [
  { date: "2022-08-15" },
  { date: "2022-08-31" },
  { date: "2022-10-19" },
  { date: "2022-10-27" },
];

const now = Date.now()
const result = arr.filter(e => new Date(e.date) > now)
console.log(result)

Another way to achieve the same result is by comparing the date strings directly based on their lexicographical order:

let todayDate = new Date().toISOString().slice(0, 10);

let arr = [
  { date: "2022-08-15" },
  { date: "2022-08-31" },
  { date: "2022-10-19" },
  { date: "2022-10-27" },
];

const result = arr.filter(e => e.date > todayDate)
console.log(result)
