What programming languages ​​are commonly used by Golang developers?

Golang is an open source programming language developed by Google and is widely used in back-end service development, cloud computing, network programming and other fields. As a statically typed language, Golang has an efficient concurrency model and a powerful standard library, so it is favored by developers. However, in actual development, Golang developers usually need to combine other programming languages ​​for project development to meet the needs of different scenarios.

1. Python
   Python is an object-oriented programming language known for its simplicity, clarity, and ease of learning. In Golang development, Python is often used to handle work in data analysis, machine learning, natural language processing and other fields. The following is a simple Python script example for counting the occurrences of each word in a piece of text:

text = "Hello world, hello Python, hello Golang"
words = text.split()
word_count = {}
for word in words:
    if word in word_count:
        word_count[word] = 1
    else:
        word_count[word] = 1
print(word_count)

2. JavaScript
   JavaScript is a scripting language commonly used in front-end development and can be used to achieve web page interaction and dynamic effects. In Golang development, JavaScript is usually used to write some front-end pages, or to communicate with the back-end through Ajax. The following is a simple JavaScript code example for sending a GET request to obtain data:

var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/data', true);
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && xhr.status == 200) {
        var data = JSON.parse(xhr.responseText);
        console.log(data);
    }
};
xhr.send();

3. SQL
   SQL (Structured Query Language) is a standardized language for database management systems that can be used to query and manage databases The data. In Golang development, SQL is often used to operate databases, such as MySQL, PostgreSQL, etc. The following is a simple SQL query example to get user information from the database:

SELECT * FROM users WHERE age > 18;

4. Shell Script
   Shell script is a scripting language used to quickly execute system commands and batch processing tasks. In Golang development, sometimes you need to use Shell scripts to start services, clear caches and other operations. Here is a simple shell script example for automatically backing up data:

#!/bin/bash
mkdir -p /backup
cp -r /data /backup/data_$(date "%Y%m%d")

To sum up, the programming languages ​​commonly used by Golang developers include Python, JavaScript, SQL and Shell scripts, etc. By combining different programming languages, project development can be carried out more flexibly, improving development efficiency and project quality.
