Reasons for transitioning to golang and learning suggestions

With the booming development of the Internet, programmers increasingly have different choices for different programming languages. The Golang language, which is the Go language developed by Google, has also become the darling of Internet developers in recent years. This article will introduce the Golang language, including technical reasons, application scenarios, learning suggestions, etc.

1. Background introduction

The Golang language was designed and developed by Robert Griesemer, Rob Pike, and Ken Thompson of Google in the fall of 2007, and was officially released in November 2009. Go language aims at system programming and has the characteristics of efficiency, reliability and flexibility. Compared with other languages, it greatly reduces programmers' code development and testing costs, while also ensuring the running speed and stability of the program.

2. Technical reasons

1. Concurrency

The most significant feature of Golang language is concurrency. Golang provides goroutine and channel at the language level, allowing programmers to complete program concurrency control with extremely low cost and code volume. Goroutine is a lightweight thread in Golang. The underlying implementation only requires a stack size of 2KB, so starting a new goroutine is very cheap. Channel is Golang's communication mechanism, which can avoid race conditions and express program dependencies very intuitively, making the code easier to understand, maintain and expand.

2. Memory Management

In Golang, memory management is the responsibility of both the compiler and the runtime. The compiler is responsible for converting the program into a series of instructions, and is responsible for dynamic management of memory at runtime. This memory management method avoids common memory leak problems and avoids the memory allocation and release problems that need to be handled manually in conventional programming languages.

3. Simplicity

The Golang language is highly restrictive. It not only has a very strict set of grammatical rules, but also supports the detection of many errors during compilation, which can It enables programmers to develop a very rigorous programming habit. At the same time, the syntax of the Golang language is very concise, not only easy to write, but also the amount of code is very small, which allows programmers to quickly implement the desired functions and also reduces code maintenance costs.

3. Application Scenarios

1. Web Development

Because the Golang language inherently supports high concurrency, it has great advantages in Web development. Compared with other web frameworks, Golang's web framework has characteristics similar to static languages, which makes it perform well in code testing and error detection. At the same time, the compilation speed of Golang language is very fast, which gives web applications developed based on Golang also have obvious advantages in deployment and operation.

2. Distributed System

The concurrency nature of Golang makes it very suitable for developing distributed systems. For example, the Golang language has very efficient TCP/IP and HTTP/2 support, which makes it very convenient for Golang to build network communication protocols such as TCP, HTTP, and RPC. At the same time, Golang also provides standard libraries (such as encoding/json, net/http, etc.). These libraries can help developers build distributed systems very conveniently, and also significantly improve developers' development efficiency.

3. Cloud native applications

Golang language is also widely used in cloud native applications. Golang can be used to write containerized applications and microservices, and can also support automation tools within the community. In addition, Golang can also be integrated with systems such as Docker and Kubernetes, which provides great convenience for the development and management of cloud-native applications.

4. Learning Suggestions

1. Learning Materials

Golang language learning materials are very rich and can be learned through official documents, Golang Chinese community, and Golang China Learn from websites such as the Internet. For beginners, you can start learning by reading books such as "Go Language Programming" and "Go Language Practical Combat".

2. Practice Project

Through actual project practice, learners can have a deeper understanding of the advantages and disadvantages of the Golang language. You can obtain Golang's open source code through Github, Gitee and other websites, and participate in project contributions.

3. Continuous learning

As the Golang language continues to develop and progress, continuous learning is also a problem that every Golang programmer must face. Therefore, you can learn by regularly reading the latest information from the Golang community and participating in relevant technology sharing meetings.

In general, Golang language has developed into a very popular programming language in recent years, with a wide range of application scenarios in big data, cloud computing, Web applications, etc. For programmers who are interested in developing Internet applications, learning Golang and applying it to actual projects will help them quickly improve their personal technical level.
