Sort an object array by custom order

Question

I have an array of objects which have a property called \'CODE\'.

[
  {
   ID: 168,
   NAME: \"First name\",
   CODE: \"AD\"
  },
  {
   ID: 167,
   NAME: \"         


        

Answer 1

For huge arrays, I suggest to use an object for the indices.

var array = [{ ID: 168, NAME: "First name", CODE: "AD" }, { ID: 167, NAME: "Second name", CODE: "CC" }, { ID: 169, NAME: "Third name", CODE: "CCM" }, { ID: 170, NAME: "Fourth name", CODE: "CR" }],
    item_order = ["CCM", "CR", "AD", "CC"],
    order = item_order.reduce((r, k, v) => Object.assign(r, { [k]: v }), {});

array.sort((a, b) => order[a.CODE] - order[b.CODE]);

console.log(array);

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