Sort An Array Of Objects Based On A Numeric Key Given As String

I have an an array with key-value pair, 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 numer

Solution 1:

items.sort((a,b)=>a.id-b.id)

Solution 2:

Use Arrays.sort()

var arr = [{"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"}];
arr.sort((a,b)=>Number(a.id) - Number(b.id));
console.log(arr);

Solution 3:

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) =>Number(a.id) - Number(b.id));
console.log(items);

Solution 4:

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"
}];

// for asscending
items.sort((a, b) =>Number(a.id) - Number(b.id));
console.log(items);
// for descending
items.sort((a, b) =>Number(b.id) - Number(a.id));
console.log(items);

Solution 5:

The numeric strings can be compared in many ways. Suppose the strings are a and b,

1. a-b
2. parseInt(a) - parseInt(b) - Reference - Java Script parseInt
3. +a - +b - Reference - Unary + operator to convert string to number
4. Number(a) - Number(b) - Reference - Javascript Global Number Object

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(function(a,b){ returnparseInt(a.id)-parseInt(b.id) }));
console.log(items.sort(function(a,b){ return a.id-b.id }));
console.log(items.sort(function(a,b){ return +a.id - +b.id }));
console.log(items.sort(function(a,b){ returnNumber(a.id)-Number(b.id) }));
