理解 Vue 的反应系统

  • Reactivity system is a key feature in the view framework, translating to '反应系统'.
  • Data added to components is bound to the component's template and triggers re-renders when data changes.
  • An experiment demonstrated binding a name to a title element which updates when clicked, setting the name to '零号' and causing a re-render to display the new value.
  • View framework handles component data to ensure its reactivity.
  • The JavaScript proxy is used for the reactivity system, allowing the interception and handling of object behaviors.
  • A created lifecycle method in components outputs this.$data in the console as a proxy object, which includes handlers for operations on object properties like name.
