What are the differences between Vue.js directives and components?

Vue.js directives are special tokens in the markup that tell the library to do something to a DOM element. Components, on the other hand, are reusable Vue instances with a name. They can contain their own data, methods, and lifecycle hooks.

Can you give me examples of directives and components?

Sure! An example of a directive is v-if, which conditionally renders elements. A component example could be a <UserProfile> component that displays user information.

When should I use a directive instead of a component?

Use directives for simple DOM manipulations or behaviors, while components are better for encapsulating complex UI elements and logic.

Are there any performance considerations between using directives and components?

Yes, components can introduce overhead due to their lifecycle management, while directives are generally lighter and faster for simple tasks.
