Sort Numerically Array of object

Question

I have an array with objects, and I want to sort them by name :

myArray = [{name: 'name10'}, {name: 'name9'}, {name: 'name1'}, {name: 'name3'}]

When I apply the sort method like this

myArray.sort((a, b) => (a.name > b.name) ? 1 : ((b.name > a.name) ? -1 : 0));

it gives me 10 just after 1

myArray = [{name: 'name1'}, {name: 'name10'}, {name: 'name3'}, {name: 'name9'}]

Can I fix this ?

Your "1" should be "01" – Ajeet Eppakayala Aug 21 '20 at 15:47 — Ajeet Eppakayala, Aug 21 '20 at 15:47

You could take String#localeCompare with options.

const array = [{ name: 'name10' }, { name: 'name9' }, { name: 'name1' }, { name: 'name3' }];

array.sort(({ name: a }, { name: b }) =>
    a.localeCompare(b, undefined, { numeric: true, sensitivity: 'base' })
);

console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }

If you want to sort the names by the number at the end:

myArray = [{name: 'name10'}, {name: 'name9'}, {name: 'name1'}, {name: 'name3'}]
myArray.sort((a,b) => {
     let aNumber = a.name.match(/\d+$/), bNumber = b.name.match(/\d+$/);
     if(aNumber && bNumber)
          return parseInt(aNumber[0]) - parseInt(bNumber[0]);
     else
          return a-b;
});
console.log(myArray);

@MajedBadawi try putting one of the fields to "name" only . it will respond with error – Ajeet Eppakayala Aug 21 '20 at 15:59
@yash can see above comment. – Ajeet Eppakayala Aug 21 '20 at 16:00
@MajedBadawi you don't need `[0]` – Ajeet Eppakayala Aug 21 '20 at 16:01
That's works Thx – Seb Aug 21 '20 at 16:06
@AjeetEppakayala I updated the answer, thanks for the comment – Majed Badawi Aug 21 '20 at 16:20
@Seb You are welcome. – Majed Badawi Aug 21 '20 at 16:20
@MajedBadawi this still won't work with one of the fields as {name: "name"} – Ajeet Eppakayala Aug 21 '20 at 16:24
