What can golang develop?

Golang (also known as go language) is a statically strongly typed, compiled language developed by Google's Robert Griesemer, Rob Pike and Ken Thompson. The Go language syntax is similar to C, but its functions include: memory safety, GC (garbage collection), structural form and CSP-style concurrent computing.

Go language is a brand new programming language launched by Google. It can greatly reduce the complexity of the code without losing application performance. It can also take advantage of the simultaneous multi-tasking of multi-core processors. It can solve the troubles of object-oriented programming and help programmers deal with trivial but important memory management issues. Compared with other programming languages, it is simple, fast, safe, parallel, interesting, open source, memory management, array safety, and compilation. Speed ​​is its characteristic.

What can golang develop?

In fact, Go language is mainly used for server-side development. It is positioned to develop "large-scale software". It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing. Internet service. The Go language allows programmers to develop quickly, and as the software continues to grow, it makes it easier for programmers to maintain and modify it. It combines the efficiency of traditional compiled languages ​​with the ease of use and expressiveness of scripting languages.

In view of the characteristics of Go language and the original intention of its design, Go language, as a server programming language, is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in Web applications, API applications, download applications, etc.; in addition, Go language is also suitable for in-memory database and cloud platform fields. Currently, many foreign cloud platforms are developed using Go.

Server programming: If you used C or C to do those things in the past, Go is very suitable for doing them, such as log processing, data packaging, virtual machine processing, file systems, etc.

Distributed systems, database agents, middleware: such as Etcd.

Network programming: This area is currently the most widely used, including Web applications, API applications, download applications, and Go's built-in net/http package basically implements all the network functions we usually use.

Development of cloud platforms: Currently, many foreign cloud platforms are developed using Go. The well-known Qiniu Cloud, Huawei Cloud, etc. all have products developed using Go and are open source.

Blockchain: There is currently a saying that technical practitioners call Go language the development language of the blockchain industry. If you study blockchain technology, you will find that many blockchain systems and applications are developed using Go. For example, ehtereum is currently the most well-known public chain, and fabric is currently the most well-known. Alliance chains, both have go language versions, and go-ehtereum is also the officially recommended version of Ethereum.

At present, Go’s domestic development and community dynamics are also good, and the number of developers is increasing.
