Go Sample Example - Basic Ticker

This repository demonstrates the usage of tickers in Go, which are used to trigger actions at regular intervals. The example showcases how to create a simple ticker that ticks every second and stops after a specified duration.

📖 Information

• This example covers basic ticker usage in Go.
• It demonstrates how to create a ticker, run it for a set amount of time, and stop it after a certain number of ticks.

💻 Code Example

package main

import (
	"fmt"
	"time"
)

func main() {

	// Tickers are used to perform an action at regular intervals for a specified duration.
	// A ticker can be created using the NewTicker function from the time package

	// Simple Ticker
	// create a ticker that ticks every 1 second

	// Create a ticker that ticks every 1 second
	ticker := time.NewTicker(1 * time.Second)

	// Stop the ticker after 5 ticks
	go func() {
		time.Sleep(5 * time.Second)
		ticker.Stop()
	}()

	// Print the tick events
	for t := range ticker.C {
		fmt.Println("Tick at", t)
	}

	fmt.Println("Ticker stopped.")
}

🏃 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 021_tickers/01_basic_ticker directory:

cd go_sample_examples/021_tickers/01_basic_ticker

4. Run the Go program:

go run main.go

📦 Output

When you run the program, you should see the following output, where the ticker prints a message every second and stops after 5 seconds:
