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

To use the chunk function from the Lodash library in TypeScript, first, you need to install the lodash package and the @types/lodash package.

You can install them using npm:

npm install lodash
npm install @types/lodash

After installing the packages, you can import the chunk function from Lodash and use it in your TypeScript code as follows:

index.ts
import * as _ from 'lodash';

const array: number[] = [1, 2, 3, 4, 5, 6, 7, 8, 9];

const chunkedArray: number[][] = _.chunk(array, 3);

console.log(chunkedArray); // Output: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

In the example above, we imported the chunk function using the wildcard import syntax (import * as _ from 'lodash') and called it with an example array of numbers. The chunkedArray variable now contains a new nested array with the original array split into chunks of 3.

Note that Lodash's functions are not automatically included in the TypeScript compiler's output by default. If you use a bundler like Webpack or Rollup, make sure to configure it to include Lodash in your project.
