How do you pass an array to a function without modifying its contents inside the function?

Using timeouts to terminate goroutines in Go has the following advantages and disadvantages:

Advantages:

• Allows avoiding infinite waiting or hanging of goroutines.
• Simplifies execution time management, especially when working with external resources (e.g., network requests).
• Helps free resources if an operation takes too long.

Disadvantages:

• Timeouts can lead to premature termination of useful work if set too short.
• Additional logic is required for proper goroutine termination and resource cleanup.
• It is not always obvious how to choose the correct timeout value.

Example of using a timeout with a channel and select:

select {
case result := <-ch:
    // process result
case <-time.After(2 * time.Second):
    // timeout, interrupt waiting
}
