Here we will use the Date object to sort a date string array. Let’s use the following date array for the demonstration.
1 | const data = ["09/06/2015", "25/06/2015", "22/06/2015", "25/07/2015", "18/05/2015"]; |
Here, we’ll use the Array.prototype.sort() method with the **Date** constructor.
1 2 3 4 5 6 7 | const sorted = data.sort((a, b) => { const dtA = a.split('/').reverse().join('-'); const dtB = b.split('/').reverse().join('-'); return new Date(dtA) - new Date(dtB) }) console.log(sorted); // ['18/05/2015', '09/06/2015', '22/06/2015', '25/06/2015', '25/07/2015'] |
If the returned number is negative, then order stays the same. Otherwise, the a and b are reversed.
That’s it for today.
Thank you for reading. Happy Coding..!! 🙂
