how to use the __lookupgetter__ function from fs-extra in javascript

In JavaScript, __lookupgetter__ is a property getter that is used to define custom behavior for getting properties.

To use __lookupgetter__ function from fs-extra, you will need to first import the package:

index.tsx
const fs = require('fs-extra');

2 lines

Then, you can define a custom getter function using __lookupgetter__ as follows:

index.tsx
const myObj = {
  get myProp() {
    return 'Hello World!';
  },
};

Object.defineProperty(myObj, 'myProp', {
  __lookupGetter__: function() {
    return function() {
      return 'Goodbye World!';
    };
  },
});

console.log(myObj.myProp); // Output: Goodbye World!

In the above example, we have defined a custom getter function for myObj.myProp property. The __lookupGetter__ function returns a new getter function that overrides the default getter function of myObj.myProp property.

When we execute console.log(myObj.myProp); it causes the new getter function returned by __lookupGetter__ to be executed and it returns Goodbye World! instead of the default value Hello World!.

This is just a simple example, but __lookupGetter__ can be used to define much more complex getter functions that provide custom behavior for accessing object properties.
