What is the origin of Go language?

The Go language originated from a programming language developed by Google. It was originally designed to solve some problems existing in existing languages. Go language is a statically typed programming language. It was developed in 2007 and officially released for the first time in 2009. The designers of the Go language are Robert Griesemer, Rob Pike and Ken Thompson.

The design of the Go language is inspired by many other programming languages, including C, C, Java, Python, etc. It takes the best of these languages ​​and adds some completely new features, resulting in a powerful programming language that's easy to learn and use.

The following is a simple Go language sample code:

package main

import "fmt"

func main() {
    fmt.Println("Hello, World!")
}

This code implements a simple program that outputs "Hello, World!". Let us explain this code line by line:

• package main: Every source code file in the Go language must declare which package it belongs to. mainPackage is a special package used to identify an executable program.
• import "fmt": The import keyword is used to import the required package. The fmt package provides the function of formatting input and output. .
• func main(): Defines a function named main, which is the entry function of the program. All executable Go programs must include this function .
• fmt.Println("Hello, World!"): The Println function in the fmt package is used for printing output, which is output here "Hello, World!".

Through this simple sample code, we can see that the syntax of the Go language is concise and clear, which is very suitable for rapid development and building reliable software. Although the origin of the Go language has many references and references, its unique features and design concepts make it a popular programming language.
