Closures in Go

Go: Closures

Go supports anonymous functions, which can form closures. Anonymous functions are useful when you want to define a function inline without having to name it.

Closure example in Go


    package main

    import "fmt"

    // this will form closure 
    func outerFunction() func() int {
        x := 10
        return func() int {
            x++
            return x
        }
    }

    func main() {
        increment := outerFunction()
        fmt.Println(increment())
        fmt.Println(increment())
    }

    // 11
    // 12
