Imagine you have this line of code:
setInterval(ajaxFunction,3000);
The ajaxFunction in the code is a function that calls a PHP script and retrieves data. What if the request takes longer than 3 seconds? Will it stop the current request and begin again, or will it launch a second request while the first one is still running? Perhaps there's another outcome I haven't considered?
Both actions will coincide. Instead of using setInterval, consider utilizing setTimeout and placing it inside the oncomplete function within your ajaxFunction.
There will be an overlap. The second ajax call will start before the first one finishes.
