Pass as an Argument
Anonymous functions can be passed as arguments to other functions, especially in higher-order functions where this pattern is common.
Example:
go
package main
import "fmt"
// Higher-order function that takes a function as an argument
func applyOperation(a, b int, operation func(int, int) int) int {
return operation(a, b)
}
func main() {
// Define an anonymous function and pass it to applyOperation
result := applyOperation(3, 4, func(x, y int) int {
return x * y
})
fmt.Println(result) // Output: 12
}
3. Assign to a Variable
You can assign an anonymous function to a variable, allowing you to call it whenever needed.
Example:
go
package main
import "fmt"
func main() {
// Assign an anonymous function to a variable
greet := func(name string) {
fmt.Printf("Hello, %s!\n", name)
}
// Call the anonymous function
greet("Alice") // Output: Hello, Alice!
greet("Bob") // Output: Hello, Bob!
}
