The hook function in Vue is a special function that allows developers to execute custom code at specific stages of the component life cycle. This allows developers to perform specific tasks when components are created, updated, and destroyed, thereby increasing code flexibility.

There are the following main hook functions in Vue:

• beforeCreate: Called immediately after the instance is initialized, after creation Before virtual DOM.
• created: Called immediately after the instance is created and before mounting.
• beforeMount: Called immediately before the virtual DOM is mounted to the real DOM.

• beforeUpdate: Called immediately before re-rendering the DOM, after the virtual DOM responds to data changes.
• updated: Called immediately after the DOM is updated, after the virtual DOM is updated.
