-The synchronous API has the downside of loading the entire JSON array in memory and blocking javascript's event loop while processing the data. This means that you server won't be able to process more request or your UI will become irresponsive while data is being processed. For those reasons, is rarely a good reason to use it unless your data is very small or your application doesn't do anything else.
