how to use the __definegetter__ function from lodash in javascript

The _.defineGetter function from Lodash can be used to define a getter function on an object. This allows you to specify a function that will be called when a specific property of the object is accessed.

Here's an example of how to use _.defineGetter:

index.tsx
// Require lodash library
const _ = require('lodash');

// Define our object
const person = {
  firstName: 'John',
  lastName: 'Doe'
};

// Define our getter function
const fullNameGetter = _.property(['firstName', 'lastName']);

// Define our getter
_.defineGetter(person, 'fullName', fullNameGetter);

// Access the getter
console.log(person.fullName); // "John Doe"

In this example, we use the _.defineGetter function to define a getter for the fullName property of the person object. The getter function is defined using the _.property function from Lodash, which creates a new function that returns the value of a nested object property. We pass an array of property names to _.property.

Finally, we access the fullName property of the person object, and the getter function is called, returning the full name of the person.
