Course Introduction：Provide and inject in Vue are mechanisms for cross-level component communication. The parent component provides data through the provide, and descendant components receive through inject, without passing props layer by layer or using global state management. It is suitable for sharing stable configuration data such as topics, languages, etc. When used, the parent component returns the data to be shared in the provider, and the child component declares the required fields in the inject. Default values ​​can be set to enhance fault tolerance. Note that ordinary values ​​are not responsive and need to be responsively updated using ref or reactive packaging. Unlike Vuex/Pinia, provide/inject is suitable for local sharing within component trees, while state management libraries are more suitable for complexity.

Course Introduction：Provide/inject is a mechanism in Vue for passing data across levels, suitable for sharing global state. 1.Provide provides data or methods by the parent component definition, and inject is injected by the child component declaration, without the need for intermediate components to pass. 2. Applicable scenarios include cross-level status such as shared topics, user information, international languages, etc., as well as unified configuration access during component library development. 3. Basic usage: The parent component provides responsive or static values through provide, and the child component is obtained through inject. It is recommended to use Symbol to avoid naming conflicts. 4. Notes: Responsive values can be automatically updated, and static values will not be available; you can encapsulate the use function multiplexing logic, inject can set the default value to prevent errors, combined with Ty

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.
