how to use the sortby function from the lodash library in typescript

To use the sortBy() function from the Lodash library in TypeScript, you can follow these steps:

1. Install Lodash using npm:

index.ts
npm install lodash
19 chars
2 lines

2. Import the sortBy() function from the installed Lodash library in your TypeScript file:

index.ts
import { sortBy } from 'lodash';
33 chars
2 lines

3. Define an array of objects that you want to sort:

index.ts
const items = [
  { name: 'John', age: 25 },
  { name: 'Mary', age: 30 },
  { name: 'Bob', age: 20 },
];
105 chars
6 lines

4. Use the sortBy() function with a sorting criteria to sort the array of objects:

index.ts
const sortedItems = sortBy(items, ['age']); // sorts by age
60 chars
2 lines

Alternatively, you can use a callback function as the second argument to determine the sorting criteria:

index.ts
const sortedItems = sortBy(items, (item) => item.age); // sorts by age
71 chars
2 lines

5. Use the sorted array of objects:

index.ts
console.log(sortedItems);  // [{name: 'Bob', age: 20}, {name: 'John', age: 25}, {name: 'Mary', age: 30}]
105 chars
2 lines

The sortBy() function from the Lodash library is a powerful tool to sort arrays of objects using criteria based on object properties or a callback function. It is a useful utility function for functional programming in both TypeScript and JavaScript environments.
