Title:	Go Tip: Use defer for Clean and Safe Resource Management
Language:	Go
Description:	In Go, the defer keyword is used to ensure that a function call is performed later in the program’s execution, usually for cleanup purposes. This is particularly useful for managing resources like file handles, database connections, or locks.
Code Example:	Suppose you are working with a file that needs to be closed after processing: package main import ( "fmt" "os" ) func main() { file, err := os.Open("example.txt") if err != nil { fmt.Println("Error opening file:", err) return } // Ensure the file is closed when the function ends defer file.Close() // Process the file // ... }
