How to create a new buffer using the bytes package in Go?

To create a new buffer using the bytes package in Go, you can follow these steps:

  1. Import the bytes package:
import "bytes"
  1. Create a new buffer using the NewBuffer function:
buffer := bytes.NewBuffer(nil)

The nil argument passed to NewBuffer initializes the buffer with an empty byte slice.

  1. Use the Write method to add data to the buffer:
buffer.Write([]byte("Hello, World!"))

Here, we are writing the bytes of the string "Hello, World!" to the buffer.

  1. Use the buffer as needed, for example, reading the data using the Read method:
data := make([]byte, 12) buffer.Read(data)

Here, we are reading 12 bytes from the buffer into the data slice.

That's it! You have created a new buffer using the bytes package in Go and performed some basic operations on it.
