NodeJS how to call same function from within without recursively

If you want to call the same function within Node.js without causing recursion, you can use the setImmediate function. The setImmediate function schedules the specified function to be executed in the next iteration of the event loop, effectively allowing the current call stack to clear before the next call.

function myFunction() {

  console.log('Executing myFunction');

  // Using setImmediate to call the same function without recursion

  setImmediate(() => {

    console.log('Calling myFunction again');

    myFunction(); // This call is not recursive

  });

}

// Call the function for the first time

myFunction();

In this example, myFunction is initially called, and within its execution, setImmediate is used to schedule the next call to myFunction. This ensures that the second call is not considered recursive because it occurs in a separate iteration of the event loop.

Keep in mind that this approach is useful in certain situations, but it doesn't guarantee that the function won't be called again until the next event loop iteration. Depending on your use case, this behavior may or may not be suitable. If you need more fine-grained control over when the function is called, you might need to use other mechanisms like timers, promises, or callback functions.
