Let's understand, what is a closure and recursive / recursion function, and can closure be recursive in Golang?

Yes, a closure can also be recursive, but this requires the closure to be declared with a typed var explicitly before it's defined.

Consider the below example,

package main

import "fmt"

func main() {
	// Recursive closure function
	var InfinitePrinting func()
	InfinitePrinting = func() {
		fmt.Println("Hello")
		InfinitePrinting()
	}

	// The function calling
	InfinitePrinting()
}

Output:

Hello
Hello
Hello
Hello
Hello
.
.
.
Infinite time
