- [Instructor] Let's talk about the ways context can be used in your Go application. The four main use cases for context in your Go package are Go routines, database transactions, HTTP requests, and testing. Let's dive a little bit into each of them. The context package, when used with goroutines, provide a mechanism for creating a context that can be canceled or timed out. When a context is gracefully terminated, all goroutines associated with that context are also terminated. This prevents leaking resources or continuing unnecessary work, which ensures overall stability and performance of your program. The context package, when used in database transactions, is leveraged by associating a single context with a database transaction. This propagates the cancellation signals or deadlines for database operations in a transaction, which ensures data consistency and prevents conflicts. For HTTP, request context is used for carrying request-specific information and managing cancellation…
