Why the Composition API exists in Vue - Quick Recap

Recall & Review

beginner

What problem does the Composition API solve in Vue?

It helps organize and reuse code better, especially in large components where Options API can get messy.

beginner

How does the Composition API improve code reuse compared to the Options API?

It groups related logic together in functions, making it easier to share and maintain across components.

intermediate

Why can the Options API become hard to maintain in big projects?

Because it separates code by options like data, methods, and lifecycle hooks, making related logic scattered and harder to follow.

intermediate

What is a key benefit of the Composition API for TypeScript users?

It offers better type inference and easier integration with TypeScript compared to the Options API.

beginner

How does the Composition API help with logic organization?

It allows grouping related reactive state and functions together, making components cleaner and logic easier to understand.

Why was the Composition API introduced in Vue?

A To better organize and reuse component logic

B To replace templates with JSX

C To remove reactivity from Vue

D To make Vue slower

The Composition API was introduced to help developers organize and reuse logic more easily in Vue components.

Which problem does the Options API have that the Composition API addresses?

A Scattered related code across options like data and methods

B No support for templates

C Lack of lifecycle hooks

D No support for components

The Options API separates code by options, which can scatter related logic and make maintenance harder.

How does the Composition API group code?

A By file size

B By HTML elements

C By related logic and functionality

D By CSS styles

The Composition API groups code by related logic, making it easier to understand and reuse.

What is a benefit of the Composition API for TypeScript users?

A Removes the need for types

B Better type inference and integration

C Disables reactivity

D Forces use of classes

The Composition API works well with TypeScript, providing better type support.

Which Vue API style is better for organizing complex logic?

A Neither supports logic organization

B Options API

C Both are equally bad

D Composition API

The Composition API is designed to organize complex logic better than the Options API.
