Here array containing the name along with the updatedTimeStamp propery. I want to sort the array based on the updatedTimeStamp property.
So I am hereby using date-fns library and I want to use this library only , I can do without this library but that's my requirement to use this library.
I can able to do sort based on the updatedTimeStamp but its not return the name how can I return the name property along with updatedTimeStamp.
import { compareDesc } from "date-fns";
let arr = [
{
name:"abc",
updatedTimeStamp: "2021-12-06 14:09:00.304464"
},
{
name:"xyz",
updatedTimeStamp: "2021-12-14 13:41:58.708262"
},
{
name:"thomas",
updatedTimeStamp: "2021-12-06 15:39:09.365793"
},
{
name:"Robin",
updatedTimeStamp: "2021-12-14 09:15:42.141081"
},
{
name:"Jobin",
updatedTimeStamp: "2021-12-14 12:50:29.723421"
},
{
name:"Tobin",
}
];
const objArr = arr.map(i => i.updatedTimeStamp).sort(compareDesc)I would do it like this instead. You can pas your own function which returns the comparsefunc instead
import {
compareDesc
} from "date-fns";
let arr = [{
name: "abc",
updatedTimeStamp: "2021-12-06 14:09:00.304464"
},
{
name: "xyz",
updatedTimeStamp: "2021-12-14 13:41:58.708262"
},
{
name: "thomas",
updatedTimeStamp: "2021-12-06 15:39:09.365793"
},
{
name: "Robin",
updatedTimeStamp: "2021-12-14 09:15:42.141081"
},
{
name: "Jobin",
updatedTimeStamp: "2021-12-14 12:50:29.723421"
}
];
// careful since this modifies the original array
arr.sort((a, b) => compareDesc(a.updatedTimeStamp, b.updatedTimeStamp))
// to not mutate the original you can do this
const objArr = [...arr].sort((a, b) => compareDesc(a.updatedTimeStamp, b.updatedTimeStamp))I can do without this library but that's my requirement to use this library.
Why? The date format you have can be sorted with a normal built-in sort
let arr = [
{
name:"abc",
updatedTimeStamp: "2021-12-06 14:09:00.304464"
},
{
name:"xyz",
updatedTimeStamp: "2021-12-14 13:41:58.708262"
},
{
name:"thomas",
updatedTimeStamp: "2021-12-06 15:39:09.365793"
},
{
name:"Robin",
updatedTimeStamp: "2021-12-14 09:15:42.141081"
},
{
name:"Jobin",
updatedTimeStamp: "2021-12-14 12:50:29.723421"
},
{
name:"Tobin",
}
];
const objArr = arr.slice(0).sort((a,b) => {
if (a.updatedTimeStamp > b.updatedTimeStamp) return 1
if (a.updatedTimeStamp < b.updatedTimeStamp) return -1
return 0
})
console.log(objArr)
