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

To use the writeJsonSync function from fs-extra, you will first need to install the fs-extra package. You can do this by running the following command in your terminal:

index.tsx
npm install fs-extra

Once you have installed fs-extra, you can use the writeJsonSync function like so:

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

const data = {
  name: 'John Doe',
  email: 'john.doe@example.com',
};

try {
  fs.writeJsonSync('data.json', data);
  console.log('Data written to file');
} catch (err) {
  console.error(err);
}

In the above example, data is an object that we want to write to a JSON file called data.json. We call the writeJsonSync function, passing in the filename and the data object. If the write is successful, we log a success message to the console. If there is an error, we log the error to the console.

It's important to note that writeJsonSync will overwrite any existing content in the file, so be careful when using it. If you want to append data to an existing JSON file, you should use writeJson instead.
