As shown in the figure:
Question 1: There is a red line under the request, that is, there is a gap between the fifth request and the sixth request, that is, there is a gap between the end of the fifth request and the beginning of the sixth request. Why
Question 2: In our projects, some requests are synchronous and some are asynchronous. For example, the second and third requests start at the same time. May I know which are synchronous and which are asynchronous in our daily projects?
I’d like to thank you very much if you can dispel my doubts.
The browser loading js will block the page.
XHRThe requests are all asynchronous.
