What is Vue.js, what is it used for, and what is the scope of application?
Personal superficial understanding is not as incisive and accurate as the great gods, you can Baidu by yourself; but I only pay attention to one point, that is, it is very popular, it can realize multi-view single-page Web applications, and has a broad future; it does not support IE8 and below, because in Vue is not recognized in these IE versions, and an error will be reported.
