Anonymous Functions in Golang
An anonymous function is a function that was declared without any named identifier to refer to it. Anonymous functions can accept inputs and return outputs, just as standard functions do.
Assigning function to the variable.
Anonymous functions can be used for containing functionality that need not be named and possibly for short-term use.Example
package main
import "fmt"
var (
area = func(l int, b int) int {
return l * b
}
)
func main() {
fmt.Println(area(20, 30))
}
Example
Passing arguments to anonymous functions.
package main
import "fmt"
func main() {
func(l int, b int) {
fmt.Println(l * b)
}(20, 30)
}
Example
Function defined to accept a parameter and return value.
package main
import "fmt"
func main() {
fmt.Printf(
"100 (°F) = %.2f (°C)\n",
func(f float64) float64 {
return (f - 32.0) * (5.0 / 9.0)
}(100),
)
}
