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

To use the clone function from the Underscore library in TypeScript, first you need to install the Underscore library via npm:

npm install underscore

Then, in your TypeScript project, import the clone function from the Underscore library as follows:

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

const obj = {a: 1, b: 2, c: 3};
const clonedObj = _.clone(obj);

console.log(obj); // {a: 1, b: 2, c: 3}
console.log(clonedObj); // {a: 1, b: 2, c: 3}

In the above example, we are importing the _ namespace, which contains all of the Underscore library functions. We then create an object obj with some properties, and clone it using the _.clone function. The clonedObj will be an exact copy of the obj object.

Please note that the clone function creates a shallow copy of the object. If you need to create a deep copy, you can use _.cloneDeep. Also, keep in mind that the use of functional programming paradigms and immutable objects can often eliminate the need for cloning objects in the first place.
