Sorting an array of objects by property values - JavaScript
Suppose, we have an array of objects like this −
const homes = [
{
"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 sorts the objects by the price property in ascending or descending order.
Example
Following is the code −
const homes = [
{
"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 sortByPrice = arr => {
arr.sort((a, b) => {
return parseFloat(a.price) - parseFloat(b.price);
});
};
sortByPrice(homes);
console.log(homes);Output
This will produce the following output on console −
[
{
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'
}
]
