What are life cycle hooks in VueJs?

-

  • beforeCreate - The first component in the creation of hooks. This allows us to perform actions before our component has been added to DOM. We don't have access to DOM inside of this hook.
  • Created -This hook is invoked when Vue has set up events and data observations. Here, events are active and access to reactive data is enabled through templates that have not yet been mounted or rendered.
  • beforeMount - The beforeMount hooks runs right before the initial render happens and after the template or render functions have complied.
  • Mounted - This is a most used hook and you will have full access to the reactive component, templates, and rendered DOM (via. this.$el). The most frequently used patterns are fetching data for your component.
  • beforeUpdate - This hook runs after data changes on our component and the update cycle begins. But it runs right before the DOM is patched and re-renders.
  • Updated - This hook runs after data changes on your component and the DOM re-renders.
  • beforeDestroy -  This hook will run before destroying the Vue instance.
  • Destroyed - This hook is called after your component has been destroyed, its directives have been unbound and its event listeners have been removed

Is it always necessary to create objects from class? No. An object is necessary to be created if the base class has non-static methods. But if the class has static methods, then objects don’t need to be created. You can call the class method directly in this case, using the class name. How much memory does a class occupy? Classes do not consume any memory. They are just a blueprint based on which objects are created. Now when objects are created, they actually initialize the class members and methods and therefore consume memory. Can you create an instance of an abstract class? No. Instances of an abstract class cannot be created because it does not have a complete implementation. However, instances of subclass inheriting the abstract class can be created.
