Go Sample Example - Panic with Defer

This repository demonstrates the use of panic along with defer in Go. It showcases how deferred functions are executed even in the event of a panic, making them useful for cleanup tasks or ensuring certain operations are completed.

📖 Information

• This example covers the usage of `panic` and `defer` in Go.
• The `panic` function triggers a panic that halts normal execution, while the `defer` function ensures that certain code will still run after a panic, typically for cleanup or logging purposes.
• This technique can help ensure that important operations, such as resource deallocation, are still performed when an error occurs.

💻 Code Example

package main

import (
	"fmt"
)

func main() {

	// Deferred functions will still run even if a panic occurs. This is useful for cleanup tasks.

	defer fmt.Println("This will run even if panic occurs")
	panic("Panic in main function")
	fmt.Println("This will not be printed")
}

🏃 How to Run

1. Make sure you have Go installed. If not, you can download it from here.

2. Clone this repository:

   git clone https://github.com/Rapter1990/go_sample_examples.git

3. Navigate to the 027_panic_and_defer/006_panic_with_defer directory:

   cd go_sample_examples/027_panic_and_defer/006_panic_with_defer

4. Run the Go program:

   go run main.go

📦 Output

When you run the program, you should see the following output:

This will run even if panic occurs
panic: Panic in main function
