Formatting an array of objects to CSV

This feature allows you to easily convert an array of objects into a CSV string. The example demonstrates how to use the `writeToString` method to convert an array of objects into a CSV format string, including headers.

const { writeToString } = require('@fast-csv/format');
const rows = [
  { id: 'A1', name: 'John Doe' },
  { id: 'A2', name: 'Jane Doe' }
];
writeToString(rows, { headers: true })
  .then(csvString => console.log(csvString));

Streaming data to CSV

This feature demonstrates how to stream data to a CSV file. It uses the `format` function to create a stream that formats objects into CSV format and pipes the output to a file. This is useful for handling large datasets or real-time data processing.

const { createWriteStream } = require('fs');
const { format } = require('@fast-csv/format');
const stream = format({ headers: true });
stream.pipe(createWriteStream('path/to/file.csv'));
stream.write({ id: 'A1', name: 'John Doe' });
stream.write({ id: 'A2', name: 'Jane Doe' });
stream.end();
