or you ' re doing this quite often.Using RxJS:varSource = Rx.Observable.fromArray ([1,2,3,4,5,6]); Source.filter (function(x) {Console.log ("Filter:" +x); returnX%2==0;}).

, so there was a problem and I couldn't locate the cause as soon as possible. If such problems often occur, it is bound to waste a lot of time and energy.So, start optimizing.First, just mentioned, record the full log for troubleshooting.Second, the most important, "Handle the exception, refresh the page retry!" "This is a very empty hint, by modifying the program, instead of prompting for clear reasons.Thirdly, in the list of orders to be processed, each line has a "dispatch" button, and the di
