Sorting an array by date with Moment.js

sorting-an-array-by-date-with-moment-js.md

const Moment = require('moment')
const array = [{date:"2018-05-11"},{date:"2018-05-12"},{date:"2018-05-10"}]
const sortedArray  = array.sort((a,b) => new Moment(a.date).format('YYYYMMDD') - new Moment(b.date).format('YYYYMMDD'))
console.log(sortedArray)

Nice

For sorter we can use with Lodash
Ex:

const sortedArray = _.orderBy(array, (o: any) => {
      return moment(o.date.format('YYYYMMDD');
    }, ['asc']);

(or 'desc')

The following also takes seconds and milliseconds into account and is a bit shorter.

let sortedArray = array.sort((a, b) => a.valueOf() - b.valueOf())

I appreciate you people, thanks for this.

Same as @SijmenHuizenga suggested but a bit more readable since .unix() returns unix epoch.

let sortedArray = array.sort((a, b) => a.unix() - b.unix())

Where a and b are moment objects.

May I suggest moment().diff?

const sortedArray = array.sort((a, b) => a.diff(b))

diff takes the usual moment input, e.g. a date-formatted string.

@jonasholtkamp thank you for sharing the shortest (and to me most elegant) way!

how can we do on this on react native

how can we do on this on react native

moment is supported by react native so the code does not change.

@SijmenHuizenga Man, thanks!

thanks

Thanks for this post everyone!

@jonasholtkamp thanks!

You guys rock!

Working smoothly!

@jonasholtkamp thanks!

Thanks for this aport. Using moment in the code will be so:

let sortedArray = array.sort((a,b) => moment(a).valueOf() - moment(b).valueOf())

simple and clear, thanks!

This worked for me really nicely! thanks @jonasholtkamp

Thanks a lot!

Thaknks!

Thanks.

Thanks!!! <3 here I am after trying everything... loving you for this! (and dancing for victory of course!)
