If you need to sort an array of objects by their property values using Javascript, then you don’t need to look further than the built-in sort functionality.
Step 1 – Create an array of objects to work with
let people = [
{
name : "John",
surname : "Doe",
age : 21
}, {
name : "Jack",
surname : "Bennington",
age : 35
}, {
name : "Jane",
surname : "Doe",
age : 19
}
];
Step 2 – Sort by keys
Option 1 – Sort by surname
people.sort((a, b) => a.surname.localeCompare(b.surname));
console.log(people);
This will give you the following output:
[
{name: 'Jack', surname: 'Bennington', age: 35},
{name: 'John', surname: 'Doe', age: 21},
{name: 'Jane', surname: 'Doe', age: 19}
]
Option 2 – Sort by age
people.sort((a, b) => {
return a.age - b.age;
});
console.log(people);
This will give you the following output:
[
{name: 'Jane', surname: 'Doe', age: 19},
{name: 'John', surname: 'Doe', age: 21},
{name: 'Jack', surname: 'Bennington', age: 35}
]
