package main

import "fmt"

var f = func() {
	fmt.Println("匿名函数作为变量来使用")
}

func main() {
	f()

	func() {
		fmt.Println("匿名函数直接使用")
	}()
}

匿名函数作为变量来使用
匿名函数直接使用

package main

import "fmt"

func main() {
	str := "Hello World"

	func() {
		str = "How are you"
	}()

	fmt.Println(str)
}

How are you

package main

import "fmt"

func main() {
	str := "Hello World"

	defer func() {
		fmt.Println("defer str=", str)
	}()

	str = "Are you OK?"
	fmt.Println("main str =", str)
}

main str = Are you OK?
defer str= Are you OK?
