compare-func

Sorting by property name

This feature allows sorting an array of objects based on a specific property. In the provided code, an array of users is sorted by the 'age' property.

const compare = require('compare-func');
let users = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 20 },
  { name: 'Carol', age: 30 }
];
users.sort(compare('age'));
console.log(users);

Sorting by multiple criteria

This feature enables sorting based on multiple properties. The array of users is first sorted by 'name' and then by 'age' if the names are the same.

const compare = require('compare-func');
let users = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 20 },
  { name: 'Carol', age: 30 }
];
users.sort(compare(['name', 'age']));
console.log(users);

Sorting using a custom getter function

This feature allows for sorting using a custom function that defines the sorting criteria. Here, users are sorted based on the length of their names.

const compare = require('compare-func');
let users = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 20 },
  { name: 'Carol', age: 30 }
];
users.sort(compare(u => u.name.length));
console.log(users);
