delete a json file in javascript

To delete a JSON file in JavaScript, you can use the fs module of Node.js. Here's an example code block that shows how to do this:

const fs = require('fs');

const filename = 'example.json';

fs.unlink(filename, (err) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(`${filename} has been deleted.`);
});

In the example above, we first import the fs module and define the filename of the JSON file we want to delete. We then use the fs.unlink() method, which deletes the specified file from the filesystem.

The method takes two arguments:

• filename: a string that specifies the name or path of the file to be deleted
• callback: a function that is called after the file has been deleted, or if an error occurs. The err parameter in the callback function holds the error object if one occurred.

Once the file has been successfully deleted, the console will log a message indicating that the file has been deleted.
