Sorting an array by price in JavaScript
Suppose we have an array of objects that contains data about some houses and price like this −
const arr = [
{
"h_id": "3",
"city": "Dallas",
"state": "TX",
"zip": "75201",
"price": "162500"
},
{
"h_id": "4",
"city": "Bevery Hills",
"state": "CA",
"zip": "90210",
"price": "319250"
},
{
"h_id": "5",
"city": "New York",
"state": "NY",
"zip": "00010",
"price": "962500"
}
];We are required to write a JavaScript function that takes in one such array. The function should sort the array (either in ascending or in descending) order according to the price property of the objects (which currently is a string).
Example
The code for this will be −
const arr = [
{
"h_id": "3",
"city": "Dallas",
"state": "TX",
"zip": "75201",
"price": "162500"
},
{
"h_id": "4",
"city": "Bevery Hills",
"state": "CA",
"zip": "90210",
"price": "319250"
},
{
"h_id": "5",
"city": "New York",
"state": "NY",
"zip": "00010",
"price": "962500"
}
];
const eitherSort = (arr = []) => {
const sorter = (a, b) => {
return +a.price - +b.price;
};
arr.sort(sorter);
};
eitherSort(arr);
console.log(arr);Output
And the output in the console will be −
[
{
h_id: '3',
city: 'Dallas',
state: 'TX',
zip: '75201',
price: '162500'
},
{
h_id: '4',
city: 'Bevery Hills',
state: 'CA',
zip: '90210',
price: '319250'
},
{
h_id: '5',
city: 'New York',
state: 'NY',
zip: '00010',
price: '962500'
}
]
