Run async function in setInterval

To execute an async function repeatedly using setInterval in JavaScript, you can directly pass the async function as the first argument to setInterval.

Important Considerations: 

• Overlapping Executions:

  If your async function takes longer to complete than the specified interval, subsequent executions might overlap. This can lead to unexpected behavior if your function is not designed to handle concurrent executions (i.e., it's not "reentrant").

• Error Handling:

  It is crucial to include try...catch blocks within your async function when using setInterval to handle potential errors. Uncaught errors in an async function called by setInterval can lead to the interval stopping or other issues.

• Alternatives for Sequential Execution:

  If you need to ensure that each async function execution completes before the next one starts, consider using a recursive setTimeout pattern or libraries designed for managing asynchronous intervals (e.g., set-interval-async from npm).

async function myAsyncFunction() {
    console.log("Async function started.");
    // Simulate an asynchronous operation, e.g., fetching data
    await new Promise(resolve => setTimeout(resolve, 1000));
    console.log("Async operation completed.");
}

// Call myAsyncFunction every 2 seconds
const intervalId = setInterval(myAsyncFunction, 2000);

// To stop the interval after some time (optional)
setTimeout(() => {
    clearInterval(intervalId);
    console.log("Interval stopped.");
}, 10000);
