How to remove a date than is lower than today's date in array of objects-CodePudding

I would like to remove a date from an object than is lower than today's date: e.g. Today is: 2022-08-17 and I got { 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 and this object should be removed
  { date: "2022-08-31" },
  { date: "2022-10-19" },
  { date: "2022-10-27" },
];

// result after filter 

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

CodePudding user response：

Parse the date with the Date constructor, then check whether it is greater than the current date:

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)

Alternatively, you could compare the strings lexographically:

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)
