Revealing the secrets of Go language: you can write wonderful code without semicolons

The Go language does not require a semicolon to end statements, which brings the following advantages: eliminating redundant code and improving code readability. Powerful syntax parser automatically detects where statements end. Ensure code consistency and simplify collaboration and code review.

Revealing the Go language: You can write wonderful code without semicolons

The Go language is famous for its concise and elegant syntax , one of its biggest features is that there is no need to use a semicolon to end the statement. This feature may seem strange, but it offers numerous advantages.

Eliminate redundant code

Semicolons are mandatory in most programming languages, but in Go language, they are redundant. This eliminates redundant code, making the code more readable and maintainable.

Example 1: Go language code without semicolon

func main() {
    fmt.Println("Hello, Go!")
    var x int = 10
}

Automatic syntax analysis

The Go language compiler passes the powerful The syntax parser automatically detects the end position of the statement. This means developers don't have to add semicolons manually, the compiler does it automatically.

Consistency

This feature of the Go language ensures code consistency. No matter who wrote the code, it will always be semicolon-free, which simplifies collaboration and code review.

**Practical Case: Web Service》

Let us understand how the Go language is used in practical applications through an example:

Example 2: A simple Go Language Web Service

package main

import (
    "fmt"
    "net/http"
)

func main() {
    // 监听端口 8080
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "Hello, web!")
    })
    http.ListenAndServe(":8080", nil)
}

In this example, we define a simple Web service that listens on port 8080 and responds to HTTP requests. Note that no semicolons are used in the code, but it still works fine.
