Sort an array of objects based on a numeric key given as String values [duplicate]

Question

I have an array with key-value pairs, array columns are id and name. I want to sort this array by id.

The id column value is of type string type but I want to sort them as numeric values also should work on IE

Here is my code:

var items = [{
    "id": "165",
    "name": "a"
  },
  {
    "id": "236",
    "name": "c"
  },
  {
    "id": "376",
    "name": "b"
  },
  {
    "id": "253",
    "name": "f"
  },
  {
    "id": "235",
    "name": "e"
  },
  {
    "id": "24",
    "name": "d"
  },
  {
    "id": "26",
    "name": "d"
  }
];

console.log(items.sort((a, b) => Number(a.ID) - Number(b.ID)))

Though the order does change it doesn't change as expected also in IE an error is thrown.

You can use sort function. developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… — Powkachu

@Anshul "it's not working" is not very helpful. What isn't working? Please add more details to your question — Luca Kiebel

Now you can do it with pure JS, using the sort method..

var items = [
  {
    "id": "165",
    "name": "a"
  },
  {
    "id": "236",
    "name": "c"
  },
  {
    "id": "376",
    "name": "b"
  },
  {
    "id": "253",
    "name": "f"
  },
  {
    "id": "235",
    "name": "e"
  },
  {
    "id": "24",
    "name": "d"
  },
  {
    "id": "26",
    "name": "d"
  }
];

items.sort((a,b)=>+a.id>+b.id);
console.log(items);

Arrow functions don't work in IE

Anshul Over a year ago

You are right arrow not working on IE @Andrew Bone

Luca Kiebel Over a year ago

Then don't use Arrow functions, they aren't needed here

Andrew Bone Over a year ago

items.sort(function(a, b){return +(a.id)>+(b.id)}) should work in IE
