Describe how you would implement buffered reading and writing in Go.

  • Using the bufio package to create a buffered reader and writer.
  • Using the fmt package to perform buffered reading and writing.
  • Using the os package to implement buffered reading and writing.
  • Using the strings package to implement buffered reading and writing.
In Go, you can implement buffered reading and writing by using the bufio package. This package provides bufio.NewReader and bufio.NewWriter functions to create buffered readers and writers, respectively. Buffered reading and writing can significantly improve I/O performance by reducing the number of system calls and minimizing data copying. You can wrap an existing io.Reader or io.Writer with bufio.NewReader or bufio.NewWriter to add buffering.
