Course Introduction：Go provides a variety of plug-in architecture implementation methods. 1. Use the plugin package to load shared libraries when running on Linux/macOS, but it needs to be compiled with Go and the plug-in symbols need to be clearly signed; 2. Through interface abstraction and plug-in registration mechanism, plug-ins can be determined and called uniformly during the compilation period, which is suitable for the scenarios of co-compiling between main programs and plug-ins; 3. Remote plug-in communication is realized with HTTP or RPC, and supports cross-language and distributed deployment, which is suitable for plug-ins to run independently; it should be noted that the plug-in package supports limited support on Windows, types cannot be shared between plug-ins, hot updates need to deal with concurrency and state consistency, and the design should be as simple as possible to reduce maintenance costs.

Course Introduction：The init() function is used in Go for package initialization. The answer is that it does not accept parameters or returns values. It will be automatically executed before the main() function. It can be used to initialize complex data structures, register plug-ins or verify environmental conditions. Multiple init() functions can be defined in a package. The execution order is: the package imported first is executed first, the same package is executed in the dictionary order of the file name, and the file is executed in the declared order. Common uses include initializing variables that require multiple steps to set, registering database drivers, etc., but excessive use should be avoided to avoid affecting the testability and readability of the code. In short, init() is suitable for necessary preset settings, but it should be kept concise to ensure that the code is clear and controllable.

Course Introduction：The main differences between HTML5 compared to original HTML are reflected in four aspects: First, the introduction of semantic tags, such as,, etc., to make the page structure clearer and improve accessibility and SEO; Second, the native support for multimedia elements, and the audio and video can be played without plug-ins through tags; Third, the form function is enhanced, and a variety of new input types such as email, date, number and placeholder attributes are added to improve user experience and verification mechanism; Fourth, the document type declaration is simplified, and error handling is optimized to improve browser parsing consistency. These improvements make modern web development more efficient and more compatible.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
