Defer Functions In Golang: Everything You Need To Know
The defer keyword in Go is a powerful feature you must know! Structs are also really common in Golang and that's why I highly recommend watching this video here as well: • This is your last video about Golang Structs!
📝 Description
In this video, we dive deep into one of the most useful and powerful features in Golang—the defer keyword. This concept allows for deferred processing that executes a function just before it returns, making it especially useful for cleanup operations or handling panics. We'll look into three different use-cases: reading a file, logging the execution time of a function, and handling and recovering from panics. Each example will provide you with practical knowledge on how to use the defer keyword effectively in your Golang code.
