Buffer
A Buffer is a variable-sized buffer of bytes with Read and Write methods. The zero value for Buffer is an empty buffer ready to use. A Buffer does not have to be initialized and supports both Reader and Writer interface.
Conversion of a Buffer into a []byte:
var buffer bytes.Buffer bytes := buffer.Bytes()
Why would I use an bytes.Buffer and not a byte slice?
