What are Vue directives and their lifecycle?

What are Vue directives and how do they work?

Vue directives are special tokens in the markup that tell the library to do something to a DOM element. They are prefixed with 'v-', like v-bind or v-model.

Can you explain the lifecycle of a Vue directive?

Sure! The lifecycle of a Vue directive includes hooks like bind, inserted, update, componentUpdated, and unbind, which allow you to perform actions at different stages.

What happens in the 'bind' hook?

In the 'bind' hook, the directive is first bound to the element, and you can set up initial values or event listeners here.

How does the 'update' hook differ from 'componentUpdated'?

The 'update' hook is called whenever the value of the directive changes, while 'componentUpdated' is called after the entire component has re-rendered.
