I am working with dynamically generated date and time data and I am looking to sort them in descending order using JavaScript.
Here is an example of the data format I am dealing with:
var array= ["25-Jul-2017 12:46:39 pm","25-Jul-2017 12:52:23 pm","25-Jul-2017 12:47:18 pm"];
Any assistance on how to achieve this would be greatly appreciated.
Check out this efficient code snippet:
let dates = ["15-Oct-2021 11:30:45 am", "15-Oct-2021 11:35:22 am", "15-Oct-2021 11:32:18 am", "15-Oct-2021 11:45:18 am"];
dates.sort((first, second) => new Date(second).getTime() - new Date(first).getTime())
console.log(dates)const dates = ["12-Aug-2019 10:30:45 am", "12-Aug-2019 09:15:22 am", "12-Aug-2019 11:20:17 am"];
dates.sort(function(a, b) {
return new Date(b) - new Date(a);
});
console.log(dates);DEMO
var array= ["25-Jul-2017 12:46:39 pm","25-Jul-2017 12:52:23 pm","25-Jul-2017 12:47:18 pm"];
var dateAr = [];
for(var i=0;i<array.length;i++){
dateAr.push(new Date(array[i].replace(/-/g,'/')).getTime()); //convert to milliseconds
}
var sortAr = dateAr.sort(function (a, b) { return a - b; }); //sort the array
var resArr = [];
for(var i=0;i<array.length;i++){
resArr.push(new Date(sortAr[i])); //create date object
}
console.log(resArr);Convert date to milliseconds, then sort it and create date object from milliseconds. Use replace(/-/g,'/') to replace date strings, it is compatible with all browsers.
