Sorting "day" "week" "month" and "year"

Question

I have an array of objects from an API

[
{path: 'image', location: 'LOCATION_1', time: 'day'}
1: {path: 'image', location: 'LOCATION_2', time: 'week'}
2: {path: 'image', location: 'LOCATION_1', time: 'year'}
3: {path: 'image', location: 'LOCATION_1', time: 'week'}
4: {path: 'image', location: 'LOCATION_1', time: 'month'}
5: {path: 'image', location: 'LOCATION_2', time: 'day'}
6: {path: 'image', location: 'LOCATION_2', time: 'month'}
7: {path: 'image', location: 'LOCATION_2', time: 'year'}
]

I want to sort them based on time but when I do, it goes like

day
month
week
year

Is there any way to make it like:

day
week
month
year

I am using functional component in javascript.

In the sorting function, you are comparing with the string that's why you are getting a sorted list with alphabetic order. If you want a custom order you can create a map to follow the order.

 const data = [ {path: 'image', location: 'LOCATION_1', time: 'day'}, {path: 'image', location: 'LOCATION_2', time: 'week'}, {path: 'image', location: 'LOCATION_1', time: 'year'}, {path: 'image', location: 'LOCATION_1', time: 'week'}, {path: 'image', location: 'LOCATION_1', time: 'month'}, {path: 'image', location: 'LOCATION_2', time: 'day'}, {path: 'image', location: 'LOCATION_2', time: 'month'}, {path: 'image', location: 'LOCATION_2', time: 'year'}, ]; const timeMap = { day: 0, week: 1, month: 2, year: 3, } data.sort((a, b) => { return timeMap[a.time] < timeMap[b.time]? -1: 1; }); console.log(data);

use the sort method like this
mdn: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

 let arr = [ {path: 'image', location: 'LOCATION_1', time: 'day'}, {path: 'image', location: 'LOCATION_2', time: 'week'}, {path: 'image', location: 'LOCATION_1', time: 'year'}, {path: 'image', location: 'LOCATION_1', time: 'week'}, {path: 'image', location: 'LOCATION_1', time: 'month'}, {path: 'image', location: 'LOCATION_2', time: 'day'}, {path: 'image', location: 'LOCATION_2', time: 'month'}, {path: 'image', location: 'LOCATION_2', time: 'year'} ]; let sortBy = ["day", "week", "month", "year"] console.log(arr.sort((a,b) => sortBy.indexOf(a.time) - sortBy.indexOf(b.time)))
