What does golang do?

Go language (also known as Golang) is a programming language developed by Google. It was born out of dissatisfaction and demand for existing programming languages ​​and aims to create a better language to meet the needs of modern software development. need.

Golang is designed as an efficient, flexible, simple and reliable programming language. It is widely used in network programming, distributed systems, cloud computing, artificial intelligence and other fields. Let's take a look at what Golang is used for.

1. Network Programming

Golang’s concurrency model and efficient network programming library make it very suitable for developing network applications, such as web servers, API services, and messaging systems. Golang has a powerful built-in http package that can handle HTTP requests and responses, and a Node.js-like Goroutine that can easily handle thousands of concurrent connections.

2. Distributed System

Golang’s concurrency model has excellent performance and scalability, so it is very suitable for the development of distributed systems. Golang's standard library provides some functions for building distributed systems, such as RPC (remote procedure call), JSON-RPC, Socket, TCP, UDP, etc. Compared with other languages, Golang can more easily implement standards of other languages, such as consistent hashing, Zookeeper, etcd, etc.

3. Web Application

Golang’s high performance and scalability make it the first choice for web application development. Golang's standard library provides functions such as routing, template rendering, and Websocket. There are also some third-party libraries, such as Gin, Echo, Beego, and Martini, which can accelerate application development and deployment.

4. Database

Golang can be integrated with various types of databases, such as: MySQL, PostgreSQL, MongoDB and LevelDB, etc. Golang provides a clear API that allows developers to easily use databases in programs. It also provides some ORM frameworks, such as GORM and Xorm, to quickly build a persistence layer.

5. Artificial Intelligence

Golang’s high-performance and high-concurrency features make it an important candidate language for artificial intelligence (AI) development. Many developers use Golang to build neural networks, natural language processing (NLP) systems, image processing and machine learning (ML) applications, etc.

In short, Golang’s performance, concurrency, simplicity and maintainability make it a rapidly developing programming language that is used in more and more fields. Not only that, the learning curve of Golang is not high. A developer with a certain programming foundation can master Golang in a short time and join this programming world full of vitality and opportunities.
