how to use the sample function from the underscore library in typescript

You can use the sample function from the Underscore library in TypeScript to randomly select one or multiple elements from an array.

Here's an example:

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

const myArray = [1, 2, 3, 4, 5];

// Select a random element from the array
const randomElement = _.sample(myArray);
console.log(randomElement);

// Select multiple random elements from the array
const randomElements = _.sample(myArray, 2);
console.log(randomElements);
304 chars
12 lines

In this example, we import the Underscore library using import * as _ from 'underscore';. We then declare an array myArray with some sample data.

To select one random element from the array, we simply call _.sample(myArray);. To select multiple random elements, we pass in an additional parameter indicating how many elements we want to select, like so: _.sample(myArray, 2);.

The sample method supports arrays and objects. If you pass an object to the sample method, you will get an array of random values from the object.
