Is golang fast?
The Go language (or Golang) originated in 2007 and was officially released in 2009. Go is a very young language, and its main goal is to "combine the development speed of dynamic languages such as Python and the performance and safety of compiled languages such as C/C." (Recommended learning: go)
Go language is another attempt at programming language design and a major improvement to C-like languages. , also provides powerful network programming and concurrent programming support. Go language has many uses and can be used for network programming, system programming, concurrent programming, and distributed programming.
The launch of Go language aims to reduce the complexity of the code without losing application performance. It has the advantages of "simple deployment, good concurrency, good language design, and good execution performance". Currently, many domestic IT companies have adopted Go language to develop projects.
The Go language is sometimes described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.
Because the Go language does not have the concepts of classes and inheritance, it does not look the same as Java or C. But it achieves polymorphism through the concept of interface. The Go language has a clear and easy-to-understand lightweight type system, and there is no hierarchy between types. Therefore, it can be said that Go language is a hybrid language.
In addition, many important open source projects are developed using the Go language, including Docker, Go-Ethereum, Thrraform and Kubernetes.
Why you should learn Go language
If you want to create system programs or network-based programs, Go language is a very good choice. As a relatively new language, it was designed by experienced and respected computer scientists to address the challenges of creating large-scale concurrent network programs.
Before the emergence of the Go language, developers were always faced with a very difficult choice: whether to use a language (such as: C) that has fast execution speed but unsatisfactory compilation speed, or use a language that has fast compilation speed but not ideal compilation speed. What about languages with poor execution efficiency (such as .NET, Java), or dynamic languages that are less difficult to develop but have average execution speed?
Obviously, Go language achieves the best balance between these three conditions: fast compilation, efficient execution, and easy development.
The Go language supports cross-compilation. For example, you can develop applications that can run on Windows on a computer running a Linux system. This
is the first programming language to fully support UTF-8. This is not only reflected in the fact that it can handle strings encoded using UTF-8, but even its source file format uses UTF-8. coding. Go language is truly international!

How to configure connection pooling for Go database connections? Use the DB type in the database/sql package to create a database connection; set MaxOpenConns to control the maximum number of concurrent connections; set MaxIdleConns to set the maximum number of idle connections; set ConnMaxLifetime to control the maximum life cycle of the connection.
Golang framework vs. Go framework: Comparison of internal architecture and external features
Jun 06, 2024 pm 12:37 PM
The difference between the GoLang framework and the Go framework is reflected in the internal architecture and external features. The GoLang framework is based on the Go standard library and extends its functionality, while the Go framework consists of independent libraries to achieve specific purposes. The GoLang framework is more flexible and the Go framework is easier to use. The GoLang framework has a slight advantage in performance, and the Go framework is more scalable. Case: gin-gonic (Go framework) is used to build REST API, while Echo (GoLang framework) is used to build web applications.
How to save JSON data to database in Golang?
Jun 06, 2024 am 11:24 AM
JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.
How to find the first substring matched by a Golang regular expression?
Jun 06, 2024 am 10:51 AM
The FindStringSubmatch function finds the first substring matched by a regular expression: the function returns a slice containing the matching substring, with the first element being the entire matched string and subsequent elements being individual substrings. Code example: regexp.FindStringSubmatch(text,pattern) returns a slice of matching substrings. Practical case: It can be used to match the domain name in the email address, for example: email:="user@example.com", pattern:=@([^\s]+)$ to get the domain name match[1].

How to use predefined time zone with Golang?
Jun 06, 2024 pm 01:02 PM
Using predefined time zones in Go includes the following steps: Import the "time" package. Load a specific time zone through the LoadLocation function. Use the loaded time zone in operations such as creating Time objects, parsing time strings, and performing date and time conversions. Compare dates using different time zones to illustrate the application of the predefined time zone feature.
Golang framework development practical tutorial: FAQs
Jun 06, 2024 am 11:02 AM
Go framework development FAQ: Framework selection: Depends on application requirements and developer preferences, such as Gin (API), Echo (extensible), Beego (ORM), Iris (performance). Installation and use: Use the gomod command to install, import the framework and use it. Database interaction: Use ORM libraries, such as gorm, to establish database connections and operations. Authentication and authorization: Use session management and authentication middleware such as gin-contrib/sessions. Practical case: Use the Gin framework to build a simple blog API that provides POST, GET and other functions.
