Golang is mainly used for back-end development, but it can also play an indirect role in the front-end field. Its design goals focus on high-performance, concurrent processing and system-level programming, and are suitable for building back-end applications such as API servers, microservices, distributed systems, database operations and CLI tools. Although Golang is not the mainstream language for web front-end, it can be compiled into JavaScript through GopherJS, run on WebAssembly through TinyGo, or generate HTML pages with a template engine to participate in front-end development. However, modern front-end development still needs to rely on JavaScript/TypeScript and its ecosystem. Therefore, Golang is more suitable for the technology stack selection with high-performance backend as the core.

In Go language, channel is used for communication and synchronization between goroutines. Declare the use of make function, such as ch:=make(chanstring), send the ch

In Go, using select statements can effectively handle non-blocking channel operations and implement timeout mechanisms. Non-blocking reception or sending operations are realized through the default branch, such as 1. Non-blocking reception: if there is a value, it will be received and printed, otherwise the default branch will be executed immediately; 2. Non-blocking transmission: If there is no receiver in the channel, the sending will be skipped. In addition, timeout control can be implemented in conjunction with time.After, such as waiting for the result or returning after 2 seconds. You can also combine non-blocking and timeout behaviors, try to get the value immediately, and wait for a short time after failure, so as to improve the program's concurrent response capabilities.

When encountering a "cannotfindpackage" error, it is usually because Go cannot find the target package or dependency. The solution is as follows: 1. Check whether the import path is correct and ensure that it is consistent with the module path or directory structure; 2. Confirm that the go.mod file has been initialized and use gomodinit and gomodtidy to manage dependencies; 3. Run goget to download missing dependencies or clean the module cache; 4. Make sure to execute commands in the correct directory context, or specify the complete module relative path for construction.

In Go, if you want the structure field to use a custom field name when converting to JSON, you can implement it through the json tag of the structure field. 1. Use the json: "custom_name" tag to specify the key name of the field in JSON. For example, Namestringjson: "username"" will make the Name field output as "username"; 2. Add, omitempty can control that the output is omitted when the field is empty, such as Emailstringjson: "email,omitempty""
