* What is the role of the VUE lifecycle?
Lifecycle hook
* Which hooks are triggered the first time the page loads?
- | – beforeCreate instance has just been created, after instance initialization, data configuration before observation and events
- | – created the instance creation is immediately after the completion of the call. In this step, the instance completes the configuration of data Observer, property and method operations, and Watch/Event event callbacks. However, the mount phase has not yet started and the $EL attribute is not currently visible
- |- beforeMount (This hook is not called during server-side rendering.)
Before the template is compiled and mounted, the HTML interface is not generated and called before the mount begins: the associated render function is called for the first time. - |- activated (This hook is not called during server-side rendering.)
Called when the keep-alive component is activated (only called when the keep-alive component is activated) - |- mounted (This hook is not called during server-side rendering.)
The template has been mounted (DOM rendering is done in Mounted). This hook is not called during server-side rendering.
* Which scenarios are appropriate for each cycle?
