What are Vue directives and computed properties?

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. For example, v-bind is used to bind data to an element's attribute.

Can you explain computed properties in Vue?

Computed properties are properties that depend on other data properties. They are cached based on their dependencies, meaning they only re-evaluate when one of their dependencies changes.

How do I use a computed property with a directive?

You can use a computed property with a directive by binding it to an element. For example, you can use v-bind to bind a computed property to an element's attribute.

Can you give me an example of using both in a Vue component?

Sure! In a Vue component, you might have a computed property that formats a user's name, and you can use v-bind to display it in the template.
