Is Golang simple?

Golang, the Go programming language, is an open source programming language developed by Google. Since its release, it has been widely used around the world. One of the reasons many programmers like Golang is its simplicity.

So, is Golang simple? The answer is yes, let’s talk about why below.

  1. Simplify code

Golang aims to make code more concise, easy to understand and easy to maintain. It does away with some of the complex features and syntax commonly used in other programming languages, such as inheritance, classes, and constructors. It also follows the KISS principle (keep it simple principle), which means it encourages writing simple code without excessive abstraction and complexity.

For example, the following code is an HTTP server written in Golang:

package main

import (
    "fmt"
    "net/http"
)

func main() {
    http.HandleFunc("/", hello)
    http.ListenAndServe(":8080", nil)
}

func hello(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "hello, world\n")
}
Copy after login

Compared with other programming languages, such code is simpler, easier to understand and maintain.

  1. Reduce redundancy

Golang discourages redundant code. Many Golang built-in functions and libraries have been tested and verified, which saves Golang programmers from writing the same code repeatedly. This ultimately makes the code shorter and easier to maintain.

For example, the following example shows how to use Golang's built-in functions to avoid using redundant code:

package main

import (
    "fmt"
)

func main() {
    var a []int = []int{1, 2, 3}
    var b []int = []int{4, 5, 6}

    // 使用 append 函数可以将两个 slice 合并
    a = append(a, b...)

    fmt.Println(a)
}
Copy after login
  1. Clear code structure

Golang encourages Programmers maintain clarity of code structure while writing programs. It uses syntax layout and font style to make code easier to read and understand.

For example, Golang uses curly braces to represent blocks of code instead of using the indentation found in other programming languages. This allows programmers to not have to worry about correct indentation, thus improving code readability.

The following code example shows the code structure in Golang:

package main

import (
    "fmt"
)

func main() {
    var a int = 1
    var b int = 2

    if a < b {
        fmt.Println("a is less than b")
    } else {
        fmt.Println("b is less than a")
    }
}
Copy after login
  1. Simple syntax

The syntax of Golang is very simple and easy to learn and use. . Programmers can quickly master the basics of Golang without spending too much time memorizing various complex grammar rules.

For example, the following is a simple syntax for defining variables in Golang:

var x int = 10
Copy after login

This example is clear, simple, and easy to understand.

To sum up, Golang is a concise programming language. Its structure and syntax are designed to make code simpler, easier to understand and maintain. The real power of Golang is that it helps programmers solve business problems rather than letting them waste time writing overly complex code.
