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

To use the get function from the lodash library in Typescript, first install the library using a package manager like npm or yarn. Once you've installed lodash, you can import the get function in your Typescript file and use it like this:

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

// Demo object
const user = {
  id: 101,
  name: 'John Doe',
  contact: {
    email: 'johndoe@example.com',
    phone: {
      mobile: '1234567890',
      work: '0987654321'
    }
  }
};

// Accessing nested properties using the get function
const mobileNumber = get(user, 'contact.phone.mobile');
console.log(mobileNumber); // Output: 1234567890

// Using typescript to control the type of the values returned
type Contacts = {
  email: string;
  phone: {
    mobile: string;
    work: string;
  };
};

type User = {
  id: number;
  name: string;
  contact: Contacts;
};

const user: User = {
  id: 101,
  name: 'John Doe',
  contact: {
    email: 'johndoe@example.com',
    phone: {
      mobile: '1234567890',
      work: '0987654321'
    }
  }
};

const mobileNumber = get<User, string>(user, 'contact.phone.mobile');
console.log(mobileNumber); // Output: 1234567890

In this example, we imported the get function from lodash and used it to access the mobile property inside the phone object nested inside the contact object of user.

We also used Typescript to control the type of the values returned by the get function by specifying the types of the user object and the result of the get function.
