Before vue, the front end was basically dominated by jq. jq operates dom elements. For example, if you want to set the content of a certain div, you need to set it with $('.div'), but vue has changed this idea. You can directly use a props to bind the value in the dom. In the code, you only need to worry about how to operate the props, and the value of the div can be synchronized in real time.
