Sorting by priority

Sorting by Priority

When working with TypeScript, there may be times when you need to sort an array of objects by priority. Sorting by priority allows you to order items based on their importance or urgency. In this blog post, we will explore different solutions for sorting by priority in TypeScript.

Solution 1: Using the Array sort() method

The Array sort() method is a built-in function that can be used to sort arrays. By providing a custom compare function, we can define the sorting logic based on the priority property of the objects.


interface Item {
  name: string;
  priority: number;
}

const items: Item[] = [
  { name: 'Task 1', priority: 2 },
  { name: 'Task 2', priority: 1 },
  { name: 'Task 3', priority: 3 },
];

items.sort((a, b) => a.priority - b.priority);

console.log(items);

The code snippet above demonstrates how to sort an array of objects by priority using the Array sort() method. The compare function subtracts the priority of object ‘a’ from the priority of object ‘b’, resulting in ascending order based on priority.

Solution 2: Using the Lodash library

If you prefer a more concise and readable solution, you can utilize the Lodash library. Lodash provides a variety of utility functions, including a sortBy() function that simplifies sorting by a specific property.


import { sortBy } from 'lodash';

interface Item {
  name: string;
  priority: number;
}

const items: Item[] = [
  { name: 'Task 1', priority: 2 },
  { name: 'Task 2', priority: 1 },
  { name: 'Task 3', priority: 3 },
];

const sortedItems = sortBy(items, 'priority');

console.log(sortedItems);

In the above code snippet, we import the sortBy() function from Lodash and use it to sort the array of objects by the ‘priority’ property. The resulting sortedItems array will be ordered based on priority.

Both solutions provide a straightforward way to sort an array of objects by priority in TypeScript. Choose the solution that best fits your project requirements and coding style.

That’s it for this blog post! We hope you found these solutions helpful for sorting by priority in TypeScript. Happy coding!
