Go语言var/init/main的执行顺序

执行顺序(降序):

var
init
main

大家也可以亲自动手把下面的代码复制到Go Playground上执行看看!

示例代码

package main

var someVar = defaultVar()

func init() {
    println("main.init was called")
}

func main() {
    println("main.main was called")
}

func defaultVar() int {
    println("main.var was initialized")
    return 0
}

输出结果如下:

main.var was initialized

main.init was called

main.main was called
