problem description
creates a recursive function A that calls itself every 5 seconds, and there is a function B that websocket will push messages every once in a while. Function A will execute An in the callback of B, that is, when B pushes, but the B function will be pushed again less than 5 seconds after the first execution, so function A will execute recursively superimposed at this time.
