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

To use the zip function from Underscore in TypeScript, you will first need to install the Underscore library using Node Package Manager (NPM). This can be done by running the following command in your project folder:

npm install underscore

2 lines

Once you have installed the library, you can import the zip function in your TypeScript code as follows:

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

const names = ['Alice', 'Bob', 'Charlie'];
const ages = [25, 30, 35];
const zipped = _.zip(names, ages);

console.log(zipped);
// Output: [['Alice', 25], ['Bob', 30], ['Charlie', 35]]

As shown in the example, the zip function takes two or more arrays as arguments and returns a new array of tuples, where the tuple at index i contains the i-th element from each of the input arrays. If the input arrays are not of the same length, the returned array will have a length equal to the length of the shortest input array.

Note that Underscore is not typed for TypeScript, so you might want to consider using a TypeScript-compatible library that provides similar functionality, such as Lodash or Ramda.
