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

The __lookupSetter__ function is a built-in function in JavaScript that allows you to retrieve the setter function of a property. In the fs-extra package, this function is used to override the default stat method of the fs module.

To use __lookupSetter__ in fs-extra, you can follow the code snippet below:

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

// get the original stat function of the fs module
const originalStat = fs.__lookupGetter__('stat');
// define a new stat function
const newStat = function(path, callback) {
  console.log('The new `stat` function is called!');
  originalStat.call(fs, path, callback);
};

// override the original stat function
fs.__defineSetter__('stat', newStat);

fse.stat('/path/to/file', function(err, stats) {
  // this will call the new `stat` function

  if (err) {
    console.log(err);
  } else {
    console.log(stats);
  }
});

In this example, we first get the original stat function of the fs module using __lookupSetter__. Then, we define a new stat function that logs a message to the console and calls the original stat function. Finally, we override the original stat function with the new stat function using __defineSetter__.

When you use fse.stat to get the stats of a file, it will call the new stat function instead of the original one. Then, the new stat function will log a message to the console and call the original stat function to get the file stats.
