Is Golang a scripting language or a compiled language? Analyze one by one

Is Golang a scripting language or a compiled language? To analyze one by one, specific code examples are required

Golang, or Go language, is an open source programming language developed by Google. It was originally designed to solve some common problems in programming, such as concurrency, performance, etc. During the development process, there is often some debate about whether Golang is a scripting language or a compiled language. In order to solve this problem, we need to first understand the definitions of scripting language and compiled language, and then conduct a detailed analysis based on the characteristics of Golang.

1. The difference between scripting language and compiled language

Script language usually refers to a language that is directly executed by the interpreter. The code is executed by the interpreter line by line without the need to execute it first. Compile into binary files. Common scripting languages ​​include Python, JavaScript, etc. Scripting language has the characteristics of strong interactivity and high development efficiency.

The compiled language needs to first compile the source code into a binary executable file and then execute it. The compilation process mainly includes lexical analysis, syntax analysis, semantic analysis, code optimization and code generation. Common compiled languages ​​include C, C, Java, etc. Compiled languages ​​have the characteristics of high execution efficiency and good security.

2. Is Golang a scripting language or a compiled language?

For Golang, it is actually a compiled language. Golang's source code needs to be compiled into machine code by a compiler before it can be executed. But at the same time, Golang also has some features similar to scripting languages, such as dynamically loading libraries, interactive programming, etc. Below we use specific code examples to analyze whether Golang is a compiled language or a scripting language.

package main

import (
    "fmt"
)

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

The above is a simple Golang code example, which contains a main function to print "Hello, World!". Next, we compile this code:

go build main.go

After executing the above command, an executable file main will be generated, and then we can directly execute this executable file:

./main

The execution result will output "Hello, World!". As can be seen from this example, Golang code needs to be compiled before it can be executed, which conforms to the definition of a compiled language.

However, Golang also supports interactive programming. We can enter Golang's interactive command line mode, called REPL (Read-Evaluate-Print Loop):

go run

After entering REPL, we can directly enter Golang in the command line The code is executed. This interactive programming feature is similar to that of a scripting language, but this does not affect the fact that Golang is essentially a compiled language.

To sum up, although Golang has some characteristics of a scripting language, from the perspective of its compilation and execution process, Golang is more in line with the definition of a compiled language. So it can be concluded that Golang is a compiled language.
