To achieve asynchronous task execution, there are a few options introduced in JavaScript.setTimeout/setIntervalEventPromiseAsync/AwaitsetTimeout/setInterval is one of the first mechanisms introduced in JavaScript to simulate asynchronous operations. Since these operations are not executing in sequence, there would be a potential issue on how data/sta...
