This module is perfect for beginners to learn Go. Discover Go core constructs, advanced error handling, and networking techniques for aspiring Go programmers and Go developers.

Golang for Programmers

Go (also called Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Many developers prefer Go to other languages like C++ and Scala because of its memory management model, which allows for easier concurrency.
In this module, you will learn Go and the core constructs and techniques of the language. After going through the basics, you will then learn more advanced Go concepts like error-handling, networking, and templating. You'll learn how to program efficiently in Go by gaining knowledge of common pitfalls and patterns, as well as by building your own applications. This module is perfect for aspiring Go developers and those who are Go beginners seeking to become proficient Go programmers.

## The `bytes` package

Slices of _bytes_ are so common that Go has a `bytes` package with manipulation functions for that kind of type. It is very analogous to the strings package. Moreover, it contains a very handy type `Buffer`:
```go
import "bytes"
type Buffer struct {
  ...
}
```
It is a _variable-sized_ buffer of bytes with `Read` and `Write` methods because reading and writing an unknown number of bytes is best done buffered.

A `Buffer` can be created as a value, like:
```go
var buffer bytes.Buffer
```
or as a pointer with `new` as:
```go
var r *bytes.Buffer = new(bytes.Buffer)
```
or created with the function: 
```go
func NewBuffer(buf []byte) *Buffer
```
This creates and initializes a new Buffer using `buf` as its initial contents. It is best to use `NewBuffer` only to read from `buf`. Here, is a simple example of code writing to a buffer:
