How to Properly Handle Ticker Stop Behavior in Golang?

Handling Ticker Stop Behavior in Golang

When using a ticker channel in Golang, calling stop() will halt the channel but not close it. This behavior can lead to questions about how to handle the situation properly.

In a code example, a ticker is created and a goroutine is launched to retrieve values from its channel. After a set time, the goroutine is still running because the channel has not been closed. Hence, the issue arises: navigating this scenario effectively.

Implementing Ticker Control with a Second Channel

One solution is to employ a second channel as a control mechanism. This approach addresses concerns and provides a more controlled environment.

In the code provided in the answer, the function Every is introduced. It takes two arguments: a time duration and a function to execute at each tick. Within the Every function, a new ticker is created along with a stop channel.

A goroutine is launched to handle the ticker. The goroutine uses a select statement to monitor the ticker channel for events and the stop channel for signals to cease operation. When the Every function is called, it returns the stop channel.

In the main function, the Every function is used to schedule a task to run every second. After a certain interval, the stop channel is signaled to terminate the ticker. As a result, the goroutine exits gracefully and the program concludes.
