The problem of asynchronously requesting data overwriting?

will there be such a situation when asynchronous ajax requests are made? when 0ms makes the first request 100ms, make the second request 200ms to get the response of the first request 300ms get the response of the first request


this depends on the number of connections. If the connection is the same, it will be returned in order, otherwise it will be uncertain


request with setTimeInterval every other 100ms, return response
