Go Sample Example - Panic and Defer (Multiple defer Statements)

This repository demonstrates the usage of multiple defer statements in Go, showcasing how they are executed in a Last In, First Out (LIFO) order. The defer keyword is commonly used to schedule tasks such as resource cleanup that should occur after the surrounding function completes.

📖 Information

• This example covers the usage of multiple `defer` statements in Go.
• It shows how the `defer` statements are executed in reverse order (LIFO) after the main function completes.

💻 Code Example

package main

import (
	"fmt"
)

func main() {

	// multiple defer statements are used, they are executed in Last In, First Out (LIFO) order
	defer fmt.Println("First defer")
	defer fmt.Println("Second defer")
	defer fmt.Println("Third defer")

	fmt.Println("Executing main function")
}
