Let's talk about synchronous and asynchronous request settings in vue

Vue.js is a very popular front-end framework that supports asynchronous requests and also provides synchronous request methods. In development, sometimes we need to make synchronous requests. This article will introduce the synchronous request settings in Vue. 1. What is a synchronous request? In front-end development, we usually use asynchronous requests (such as Ajax) to interact with data from the back-end. Asynchronous request means that after sending the request, it does not wait for the request to return, but directly executes the subsequent code and waits for the data to be returned before processing. The synchronous request is to wait for the request to return after sending the request.
