What problems did the emergence of golang language solve?
Programming languages as tools have the same purpose as all other tools, which is to improve productivity. Go language is no exception. Go language also has GC and supports Erlang-style lightweight concurrency. The most valuable thing about Go language is the improvement of existing OOP. Now, no matter what language supports OOP, it can There will definitely be a huge inheritance tree, but no matter how large or elaborate the tree is designed, it is still a static structure. Once it does not match the actual problem, a bunch of Adapters will have to be written. The Go language uses completely different methods.
There is no static inheritance or implementation relationship between classes. This relationship is not determined until it is used. For example, FileInputStream in java implements the InputStream interface,
This relationship must be determined when defining FileInputStream. When defining FileInputStream in Go language, you do not need to specify the interface it wants to implement. If the method
implemented in this class happens to satisfy InputStream, then you can It can be considered that the InputStream interface is implemented. This implementation means that the Go language no longer has the various troubles that traditional OOP has, while providing the same expression capabilities and being more elegant.

There is no problem between Turing equivalent programming languages that one language can solve but the other language cannot. It is better to say that one language solves a certain problem than another language. Go language is easier in object modeling due to its innovation in OOP. Concurrency lines similar to Erlang allow the development of high-concurrency network applications. The logic complexity can be greatly reduced.
Increased productivity is a benefit.

Reading and writing files safely in Go is crucial. Guidelines include: Checking file permissions Closing files using defer Validating file paths Using context timeouts Following these guidelines ensures the security of your data and the robustness of your application.

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.

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.

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.

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].

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.

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.
