What is golang language

Golang is an open source programming language developed by Google. It combines the safety, efficiency, and readability of static programming languages ​​with the flexibility and interactivity of dynamic languages. Golang is suitable for building high-performance web applications due to its fast compilation speed, garbage collection, and concurrent programming features.

The history of Golang can be traced back to 2007, when three engineers at Google, Rob Pike, Ken Thompson, and Robert Griesemer, began working on a new programming language to solve the bottlenecks of existing languages, especially in processing Large software systems and multi-core processors. After two years of research and development, they released the first version of Golang.

Golang is a compiled language. Unlike interpreted languages, the code must be compiled and optimized by the compiler before it can be run. This compilation process is very fast because Golang's compiler is very efficient and the resulting binaries are very small. This means Golang can quickly build and deploy web applications while saving server resources and bandwidth.

Another key feature of Golang is the garbage collector. The garbage collector is an automatic memory management mechanism that automatically reclaims memory space that is no longer used or needed, thereby reducing the risk of memory leaks and DOS attacks. Golang's garbage collector is very efficient and good at handling large memory allocations, so it can effectively protect web applications from memory leaks and DOS attacks.

Golang also supports concurrent programming, which is a programming paradigm that applies multi-core CPUs and distributed computing resources. Different from the traditional thread and lock model, Golang adopts the coroutine and channel model, which can easily handle concurrent programming and reduce the risk of deadlock and race conditions. This feature makes Golang an ideal choice to easily build high-performance, scalable and reliable web applications, as well as large-scale distributed systems.

For example, many key systems within Google, such as YouTube, Google Docs, and Google Search, all use Golang, which proves Golang’s rapid development and efficiency in large-scale web applications and distributed computing. performance.

In short, Golang is a fast, safe, efficient, and easy-to-read programming language that can quickly build and deploy web applications and distributed systems. If you are a web developer or computer scientist, you may want to learn Golang. It may become your first choice language for future development.
