How does Composition API improve code reuse?

It allows grouping related logic into reusable functions called composables that can be shared across components.

beginner

When might Options API be preferred in a project?

For small or simple projects, or when the team prefers clear separation of options and easier readability for beginners.

Which API groups code by logical features rather than component options?

A Composition API

B Options API

C Both

D Neither

Composition API groups code by logical features using functions, unlike Options API which groups by options.

Which API is generally easier for beginners to understand?

A Composition API

B Options API

C Both are equally easy

D Neither

What feature of Composition API helps with TypeScript support?

A Using templates only

B Using data objects

C Using reactive refs and functions

D Using lifecycle hooks only

Composition API uses reactive refs and functions which integrate well with TypeScript types.

Which API would you choose for a very small project with simple logic?

A Composition API

B Neither

C Either one

D Options API

Options API is simpler and clearer for small projects.

What is a composable in Vue Composition API?

A A reusable function grouping related logic

B A template section

C A data property

D A lifecycle hook
