What is golang? How to apply?

Golang (also known as Go language) is an open source programming language created by Robert Griesemer, Rob Pike and Ken Thompson. Golang is mainly used for system-level programming, network programming and distributed systems.

1. Origin and History

The design of Golang began in 2007, originally by three engineers, Robert Griesemer, Rob Pike and Ken Thompson. A new programming language developed internally by Google. Their original intention was to create a programming language that was simple, efficient, reliable and had multi-threading support. After 3 years of development and testing, Golang was officially released in 2009.

2. Features and Benefits

Golang adopts a simple and easy-to-learn syntax that reduces code length compared to languages ​​like C or Java Shorter and clearer structure. At the same time, Golang also has a built-in garbage collection mechanism that can automatically recycle unused memory space, greatly reducing the probability of code errors.

In addition, Golang also has strong cloud computing support. Golang is not only easy to learn, but also can be easily integrated into existing IT infrastructure and is widely used in the field of cloud computing. For example, some high-frequency real-time services in large Internet companies are written in Golang.

3. Language features and running environment

Golang’s syntax is similar to C language, including pointers, structures, functions, etc. But unlike C, Golang uses a garbage collection mechanism, so programmers do not need to manually manage memory, which greatly reduces the difficulty of coding and the probability of errors.

In addition, Golang also has powerful concurrency processing capabilities and a built-in CSP concurrency model, which can easily handle large-scale concurrent access. Golang can also be directly compiled into machine code, which has great advantages in operating efficiency.

4. Application Scenarios

Golang has a wide range of application scenarios. For example, some of Google's internal services are written in Golang. In addition, Golang is also widely used in high-concurrency and distributed systems, such as Docker containers, Kubernetes, etc.

In the field of cloud computing, Golang also matches cloud native projects. The combination of Golang and Docker can quickly build containerized applications and improve application deployment and management efficiency. At the same time, Golang's support for large-scale concurrency also makes it one of the preferred languages ​​for handling high-load, high-concurrency distributed systems.

5. Summary

Golang is a fast, simple and efficient programming language. It has powerful concurrent processing capabilities, built-in garbage collection mechanism, and supports cross-compilation and other features. These unique properties make Golang the preferred language for dealing with highly concurrent, distributed systems.
