What is the difference between created and mounted event in VueJS?

VueJS is a model- view-view-model JavaScript framework for building user interfaces and single-page applications. It has several lifecycle hooks (not more than 8). In this article, we are going to differentiate two types of events that are part of the lifecycle of a component. 

• Created
• Mounted 

And among both of them, mounted hooks are also known as most used hooks because it is easily handled when there is no concept involved of “Server-side Rendering ” and created is more useful when we are dealing with servers and fetching data from backend API. 

Differences between Created() and Mounted() events :-

Category	Created	Mounted
Stage	It occurs at the earliest stage of the Vue lifecycle.	It occurs after the created hook is called.
Occurrence	It occurs only once in the lifecycle of component.	It can occur more than once in the lifecycle of component.
Access	It has access to component’s data, methods, mounting, and computer properties.	You need to access (or) modify the DOM of your component immediately before (or) after initial rendering.
DOM	It cannot perform DOM manipulation because event is not mounted.	It can perform DOM manipulation because event is already mounted
API’S	Generally, used for fetching data from backend API.	In mounted, we need to perform tasks like fetching data from API in created hook only.
Mounting Phase	Mounting phase is not started by this time and $el property is not available.	Here, in the mounting phase, every time component is loaded to $el.
Child Component	If the component has child elements then it is certain that even child component will have created hook initialized.	If component has child elements then there is no guarantee all the child components will be mounted.
Server-Side	This hook is especially called when we want to read data from server.	This hook is not called during server-side rendering.
