Go io Package: From Fundamentals to Advanced Practices

Mastering Go’s io Package: A Comprehensive Guide

Hello, here is Wesley, Today’s article is about io package in Go. Without further ado, let’s get started.💪

1. Preface

In programming, input and output operations are common and important parts. These operations typically involve data streaming, such as reading from a file or printing to the terminal. In Go language, these types of operations can be implemented using primitives, but for more convenient handling of IO operations, Go provides an io package that includes two core interfaces: io.Reader and io.Writer.

What is IO?

IO (Input/Output) refers to the process of data interaction between a program and external devices. For example, reading file contents, getting user input from the keyboard, or printing calculation results to the screen. These types of operations are common in most programming languages and typically require implementation through specific APIs or libraries. In Go language, these functions are provided by the io package.
