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

To use the propertyOf function from the Lodash library in TypeScript, you need to install the Lodash library first:

index.ts
npm install lodash

Then, you can import the propertyOf function from the Lodash library and use it in your TypeScript code as shown below:

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

interface User {
  name: string;
  age: number;
}

const user: User = { name: 'John Doe', age: 30 };
const getName = propertyOf<User>('name');

console.log(getName(user)); // Output: 'John Doe'

In the above example, we defined an interface User with two properties name and age. We created an object user of type User with some values. We then defined a variable getName using the propertyOf function, specifying the User interface as the type. Finally, we passed the user object to the getName function to get the value of the name property, which is 'John Doe'.

The propertyOf function returns a function that can be used to retrieve the value of a nested property within an object. In the example above, we passed in the key name to get the value of the name property within the user object.
