Sorts an array of objects alphabetically based on a given property.
|
|
|
|
- Use `Array.prototype.sort()` to sort the array based on the given property.
|
|
- Use `String.prototype.localeCompare()` to compare the values for the given property.
|
|
|
|
```js
|
|
const alphabetical = (arr, getter, order = 'asc') =>
|
|
arr.sort(
|
|
order === 'desc'
|
|
? (a, b) => getter(b).localeCompare(getter(a))
|
|
: (a, b) => getter(a).localeCompare(getter(b))
|
|
);
|
|
```
|
|
|
|
```js
|
|
const people = [ { name: 'John' }, { name: 'Adam' }, { name: 'Mary' } ];
|
|
alphabetical(people, g => g.name);
|
|
// [ { name: 'Adam' }, { name: 'John' }, { name: 'Mary' } ]
|
|
alphabetical(people, g => g.name, 'desc');
|
|
// [ { name: 'Mary' }, { name: 'John' }, { name: 'Adam' } ]
|
|
```
