The life cycle of a Go function begins when the function is called and ends when the function call completes and returns. The stages include: 1. Function definition; 2. Function call; 3. Function execution (the local variable life cycle starts from the function call and ends at the return); 4. Function return; 5. Function end (local variables are not available).
Go function life cycle
The life cycle of a function refers to the time period from the creation of the function to the end of the function. The life cycle of a function begins when the function is called and ends when the function call completes and returns.
The life cycle of a Go function involves the following stages:
Practical case
The following is a simple example of the life cycle of a Go function:
func main() { // 定义函数 func sayHello() { fmt.Println("Hello, World!") } // 调用函数 sayHello() }
In this example, sayHello
The function is defined in the main
function and is called immediately. The fmt.Println
statement in the sayHello
function will print "Hello, World!".
When the sayHello
function returns, its execution instance will be destroyed and the fmt.Println
statement in the function will no longer be available.
