1. What is Vue
Maybe many friends already know it, but I'm still verbose. Vue is a progressive framework for building user interfaces. It is the easiest and easiest framework among the three front-end frameworks.
2. Why learn Vue
As I said above, this is the simplest front-end framework, which is more friendly to novices. It is recommended that novice players start with Vue first. The simplest means that the learning cost is relatively low, and the size of Vue is smaller than the other two frameworks. Vue compresses 20kb, React compresses about 34kb, and Angular compresses about 60Kb. The core response update mechanism of Vue means that when our data is updated, the view will automatically refresh.
