In-depth exploration of the underlying technology of Go language: What language is used at the underlying level?

As an efficient and concise programming language, Go language is widely loved by developers. However, many people have always been confused about how the underlying technology is implemented. The underlying technology usually refers to the support for program execution by the compiler, runtime, garbage collector, etc. What language is the underlying language of the Go language implemented through? In this article, we will deeply explore the implementation principles of the underlying technology of the Go language and reveal what language is used at the underlying level.

First of all, what we need to understand is that the implementation of underlying technologies such as the compiler, runtime and garbage collector of the Go language is not completed using the Go language itself, but is developed with the help of the C language. This is mainly due to the fact that C language has high performance and portability and is suitable for writing system-level low-level code. The Go language was designed with interoperability with the C language in mind. In order to achieve more efficient performance and better cross-platform support, the C language was chosen as the implementation language for the underlying technology.

Below, we use specific code examples to show how the underlying technology of Go language is implemented in C language. We take the compiler as an example to demonstrate how the source code of the Go language is written in C language. The following is a simple sample code:

// example.go

package main

/*
#include <stdio.h>

void SayHello() {
    printf("Hello from C!
");
}
*/
import "C"

func main() {
    C.SayHello()
}

In this example, we insert C language code into the Go language source code. By import "C", you can call functions defined in C language in Go language by importing C language code snippets. In this example, we define a simple C function SayHello() to print "Hello from C!". In the main() function of Go language, the C function SayHello() is called, realizing the interoperability between Go language and C language.

In this way, we can see that the underlying technology of Go language is implemented by embedding C language code and utilizing the performance and portability of C language to provide more efficient underlying support. This hybrid programming method combines the simplicity and ease of use of the Go language while retaining the performance and functionality of the C language, providing strong support for the underlying technology of the Go language.

In summary, the implementation of the underlying technology of Go language relies on C language, an efficient and portable system-level programming language. Through hybrid programming, the efficiency and portability of the underlying technology of the Go language are achieved. I hope that through the introduction of this article, readers can have a deeper understanding of the implementation principles of the underlying technology of the Go language and what language is used at the underlying level.
