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

To use the intersection function from the lodash library in TypeScript, you will need to first install the lodash library using a package manager like npm in your TypeScript project. After installing, you can import the intersection function from the library and use it in your TypeScript code.

Here's an example of how to use the lodash intersection function in TypeScript:

index.ts
import { intersection } from 'lodash';

const array1 = [1, 2, 3, 4];
const array2 = [3, 4, 5, 6];

const result = intersection(array1, array2);
console.log(result); // Output: [3, 4]
183 chars
8 lines

In the above code, we first import the intersection function from the lodash library. We then define two arrays (array1 and array2) and pass them as arguments to the intersection function. The result of the function call is saved in the result variable and then printed to the console.

The intersection function takes two or more arrays as arguments and returns a new array containing elements that are present in all of the input arrays.
