How does fmt.Println work? Why I can pass an int or a string to it?
How can I make the code below work?
package main
import "fmt"
func ln(a interface{}) {
fmt.Println(a)
}
func main() {
ln(123)
ln("test")
}
For example,
package main
import "fmt"
func ln(a interface{}) {
fmt.Println(a)
}
func main() {
ln(123)
ln("test")
}
Output:
123
test
func Println(a ...interface{}) (n int, err error)
The Go fmt package uses the reflect package.
