Type your question into Google, it helps.
Reading the documentation is sometimes helpful, you know?

Answer 4

This is a type of container or buffer for storing intermediate data.
The built-in Go server processes requests in parallel. Therefore, for example, variables external to a function can be used simultaneously by several threads. If there is a chain of functions, then it is necessary to pass data as an argument, which is inconvenient.
Frameworks offer their own contexts (containers), now since version 1.7 the context is available in the standard library.
