Hello @kartik,

Currently there are three ways to write a file:

  1. fs.write(fd, buffer, offset, length, position, callback)

    You need to wait for the callback to ensure that the buffer is written to disk. It's not buffered.

  2. fs.writeFile(filename, data, [encoding], callback)

    All data must be stored at the same time; you cannot perform sequential writes.

  3. fs.createWriteStream(path, [options])

    Creates a WriteStream, which is convenient because you don't need to wait for a callback. But again, it's not buffered.

Hope it helps!!
Thank You!!
