Timeout Using Select

Overview of timeout using select

The select statement randomly selects a case from all the case statements that are ready to execute. As the name suggests, the timeout pattern that uses select exits the select clause once the timer completes. Let’s suppose we’re running an infinite loop but need to end it after x seconds. In that case, the timeout pattern that uses select is very useful.

Let’s take another scenario. Say we are organizing a quiz, and the time to answer each question is one minute. We can easily use this pattern.
